Don’t forget to name the expression - anonymous functions can make it harder to locate the problem in an Error's call stack.

Per the eslint documentation, unary increment and decrement statements are subject to automatic semicolon insertion and can cause silent errors with incrementing or decrementing values within an application.

Disallowing unary increment and decrement statements also prevents you from pre-incrementing/pre-decrementing values unintentionally which can also cause unexpected behavior in your programs.

+1. [Nesting](#nesting)
+1. [Inline](#inline)
+1. [Themes](#themes)
+
+## Naming
+
+  - Use camelCase for object keys (i.e. "selectors").
+
+  > Why? We access these keys as properties on the `styles` object in the component, so it is most convenient to use camelCase.
+
+    ```js
+    // bad
+    {
+      'bermuda-triangle': {
+        display: 'none',
+      },
+    }
+
+    // good
+    {
+      bermudaTriangle: {
+        display: 'none',
+      },
+    }
+    ```
+
+  - Use an underscore for modifiers to other styles.
+
+  > Why? Similar to BEM, this naming convention makes it clear that the styles are intended to modify the element preceded by the underscore. Underscores do not need to be quoted, so they are preferred over other characters, such as dashes.
+
+    ```js
+    // bad
+    {
+      bruceBanner: {
+        color: 'pink',
+        transition: 'color 10s',
+      },
+
+      bruceBannerTheHulk: {
+        color: 'green',
+      },
+    }
+
+    // good
+    {
+      bruceBanner: {
+        color: 'pink',
+        transition: 'color 10s',
+      },
+
+      bruceBanner_theHulk: {
+        color: 'green',
+      },
+    }
+    ```
+
+  - Use `selectorName_fallback` for sets of fallback styles.
+
+  > Why? Similar to modifiers, keeping the naming consistent helps reveal the relationship of these styles to the styles that override them in more adequate browsers.
+
+    ```js
+    // bad
+    {
+      muscles: {
+        display: 'flex',
+      },
+
+      muscles_sadBears: {
+        width: '100%',
+      },
+    }
+
+    // good
+    {
+      muscles: {
+        display: 'flex',
+      },
+
+      muscles_fallback: {
+        width: '100%',
+      },
+    }
+    ```
+
+  - Use a separate selector for sets of fallback styles.
+
+  > Why? Keeping fallback styles contained in a separate object clarifies their purpose, which improves readability.
+
+    ```js
+    // bad
+    {
+      muscles: {
+        display: 'flex',
+      },
+
+      left: {
+        flexGrow: 1,
+        display: 'inline-block',
+      },
+
+      right: {
+        display: 'inline-block',
+      },
+    }
+
+    // good
+    {
+      muscles: {
+        display: 'flex',
+      },
+
+      left: {
+        flexGrow: 1,
+      },
+
+      left_fallback: {
+        display: 'inline-block',
+      },
+
+      right_fallback: {
+        display: 'inline-block',
+      },
+    }
+    ```
+
+  - Use device-agnostic names (e.g. "small", "medium", and "large") to name media query breakpoints.
+
+  > Why? Commonly used names like "phone", "tablet", and "desktop" do not match the characteristics of the devices in the real world. Using these names sets the wrong expectations.
+
+    ```js
+    // bad
+    const breakpoints = {
+      mobile: '@media (max-width: 639px)',
+      tablet: '@media (max-width: 1047px)',
+      desktop: '@media (min-width: 1048px)',
+    };
+
+    // good
+    const breakpoints = {
+      small: '@media (max-width: 639px)',
+      medium: '@media (max-width: 1047px)',
+      large: '@media (min-width: 1048px)',
+    };
+    ```
+
+## Ordering
+
+  - Define styles after the component.
+
+  > Why? We use a higher-order component to theme our styles, which is naturally used after the component definition. Passing the styles object directly to this function reduces indirection.
+
+    ```jsx
+    // bad
+    const styles = {
+      container: {
+        display: 'inline-block',
+      },
+    };
+
+    function MyComponent({ styles }) {
+      return (
+        <div {...css(styles.container)}>
+          Never doubt that a small group of thoughtful, committed citizens can
+          change the world. Indeed, it’s the only thing that ever has.
+        </div>
+      );
+    }
+
+    export default withStyles(() => styles)(MyComponent);
+
+
+    // good
+    function MyComponent({ styles }) {
+      return (
+        <div {...css(styles.container)}>
+          Never doubt that a small group of thoughtful, committed citizens can
+          change the world. Indeed, it’s the only thing that ever has.
+        </div>
+      );
+    }
+
+    export default withStyles(() => ({
+      container: {
+        display: 'inline-block',
+      },
+    }))(MyComponent);
+    ```
+
+## Nesting
+
+  - Leave a blank line between adjacent blocks at the same indentation level.
+
+  > Why? The whitespace improves readability and reduces the likelihood of merge conflicts.
+
+    ```js
+    // bad
+    {
+      bigBang: {
+        display: 'inline-block',
+        '::before': {
+          content: "''",
+        },
+      },
+      universe: {
+        border: 'none',
+      },
+    }
+
+    // good
+    {
+      bigBang: {
+        display: 'inline-block',
+
+        '::before': {
+          content: "''",
+        },
+      },
+
+      universe: {
+        border: 'none',
+      },
+    }
+    ```
+
+## Inline
+
+  - Use inline styles for styles that have a high cardinality (e.g. uses the value of a prop) and not for styles that have a low cardinality.
+
+  > Why? Generating themed stylesheets can be expensive, so they are best for discrete sets of styles.
+
+    ```jsx
+    // bad
+    export default function MyComponent({ spacing }) {
+      return (
+        <div style={{ display: 'table', margin: spacing }} />
+      );
+    }
+
+    // good
+    function MyComponent({ styles, spacing }) {
+      return (
+        <div {...css(styles.periodic, { margin: spacing })} />
+      );
+    }
+    export default withStyles(() => ({
+      periodic: {
+        display: 'table',
+      },
+    }))(MyComponent);
+    ```
+
+## Themes
+
+  - Use an abstraction layer such as [react-with-styles](https://github.com/airbnb/react-with-styles) that enables theming. *react-with-styles gives us things like `withStyles()`, `ThemedStyleSheet`, and `css()` which are used in some of the examples in this document.*
+
+  > Why? It is useful to have a set of shared variables for styling your components. Using an abstraction layer makes this more convenient. Additionally, this can help prevent your components from being tightly coupled to any particular underlying implementation, which gives you more freedom.
+
+  - Define colors only in themes.
+
+    ```js
+    // bad
+    export default withStyles(() => ({
+      chuckNorris: {
+        color: '#bada55',
+      },
+    }))(MyComponent);
+
+    // good
+    export default withStyles(({ color }) => ({
+      chuckNorris: {
+        color: color.badass,
+      },
+    }))(MyComponent);
+    ```
+
+  - Define fonts only in themes.
+
+    ```js
+    // bad
+    export default withStyles(() => ({
+      towerOfPisa: {
+        fontStyle: 'italic',
+      },
+    }))(MyComponent);
+
+    // good
+    export default withStyles(({ font }) => ({
+      towerOfPisa: {
+        fontStyle: font.italic,
+      },
+    }))(MyComponent);
+    ```
+
+  - Define fonts as sets of related styles.
+
+    ```js
+    // bad
+    export default withStyles(() => ({
+      towerOfPisa: {
+        fontFamily: 'Italiana, "Times New Roman", serif',
+        fontSize: '2em',
+        fontStyle: 'italic',
+        lineHeight: 1.5,
+      },
+    }))(MyComponent);
+
+    // good
+    export default withStyles(({ font }) => ({
+      towerOfPisa: {
+        ...font.italian,
+      },
+    }))(MyComponent);
+    ```
+
+  - Define base grid units in theme (either as a value or a function that takes a multiplier).
+
+    ```js
+    // bad
+    export default withStyles(() => ({
+      rip: {
+        bottom: '-6912px', // 6 feet
+      },
+    }))(MyComponent);
+
+    // good
+    export default withStyles(({ units }) => ({
+      rip: {
+        bottom: units(864), // 6 feet, assuming our unit is 8px
+      },
+    }))(MyComponent);
+
+    // good
+    export default withStyles(({ unit }) => ({
+      rip: {
+        bottom: 864 * unit, // 6 feet, assuming our unit is 8px
+      },
+    }))(MyComponent);
+    ```
+
+  - Define media queries only in themes.
+
+    ```js
+    // bad
+    export default withStyles(() => ({
+      container: {
+        width: '100%',
+
+        '@media (max-width: 1047px)': {
+          width: '50%',
+        },
+      },
+    }))(MyComponent);
+
+    // good
+    export default withStyles(({ breakpoint }) => ({
+      container: {
+        width: '100%',
+
+        [breakpoint.medium]: {
+          width: '50%',
+        },
+      },
+    }))(MyComponent);
+    ```
+
+  - Define tricky fallback properties in themes.
+
+  > Why? Many CSS-in-JavaScript implementations merge style objects together which makes specifying fallbacks for the same property (e.g. `display`) a little tricky. To keep the approach unified, put these fallbacks in the theme.
+
+    ```js
+    // bad
+    export default withStyles(() => ({
+      .muscles {
+        display: 'flex',
+      },
+
+      .muscles_fallback {
+        'display ': 'table',
+      },
+    }))(MyComponent);
+
+    // good
+    export default withStyles(({ fallbacks }) => ({
+      .muscles {
+        display: 'flex',
+      },
+
+      .muscles_fallback {
+        [fallbacks.display]: 'table',
+      },
+    }))(MyComponent);
+
+    // good
+    export default withStyles(({ fallback }) => ({
+      .muscles {
+        display: 'flex',
+      },
+
+      .muscles_fallback {
+        [fallback('display')]: 'table',
+      },
+    }))(MyComponent);
+    ```
+
+  - Create as few custom themes as possible. Many applications may only have one theme.
+
+  - Namespace custom theme settings under a nested object with a unique and descriptive key.
+
+    ```js
+    // bad
+    ThemedStyleSheet.registerTheme('mySection', {
+      mySectionPrimaryColor: 'green',
+    });
+
+    // good
+    ThemedStyleSheet.registerTheme('mySection', {
+      mySection: {
+        primaryColor: 'green',
+      },
+    });
+    ```

Joe Lencioni	25123199dc	Add JavaScript Air to list of Podcasts It probably wouldn't be a bad idea for us to make a full pass on updating the resources section, but I noticed the podcasts portion was missing JS Air.	2016-09-08 08:29:10 -07:00
Joe Lencioni	68b7aeb6dd	Add rule about TC39 proposals that haven't reached stage 3 There has been some confusion around which language features should be used and which should not be used yet. We have a pretty clear-cut rule at Airbnb about this, which is do not use any TC39 proposals that have not reached stage 3. I considered putting this at the very top of the document, but I spotted this section that seemed to fit. Addresses #1057	2016-09-08 08:19:27 -07:00
Joe Lencioni	e6782493f3	Update ECMAScript 6 heading to match TOC I plan to add some information to this section that applies to ES6 and everything following ES6. Since we already list this as ES6+ in the table of contents, I figured it would be a good idea to make this match. I preserved the anchor to avoid breaking links for folks.	2016-09-08 08:11:32 -07:00

Joe Lencioni	39d5559b9a	Remove misleading reference to one-var eslint rule This eslint rule does not enforce this style guide rule. I believe that referencing it here will cause people to believe that this is enforced via linting when it is not. As far as I know, there is no rule that currently enforces this, but it would be nice to add one.	2016-08-18 10:35:23 -07:00

Joe Lencioni	dc7e7e77f2	Reverse rule on string concatenation for long lines (#995 ) Broken and concatenated long strings are painful to work with and produce less readable and searchable code. I think we should reverse this rule. Unfortunately, the max-len rule currently does not allow for this, but there is currently a proposal to add an option to ESLint's max-len rule that would allow for strings to be ignored. https://github.com/eslint/eslint/issues/5805 There have also been discussions around performance of string concatenation (https://github.com/airbnb/javascript/issues/40), but I don't think that is very relevant here so I removed the links to them.	2016-08-04 09:53:09 -07:00
Joe Lencioni	6d2fc89bd1	Add template literal "bad" example to single quotes guideline There has been some confusion around whether we should use single quotes or template literals. To help avoid this confusion, I am adding a "bad" example to the single quotes guideline. This rule is already enforced by the quotes linter rule. Generally, we want code to clearly express developer intention. Using template literals communicates that you intend to use some of the features that template literals offer (e.g. interpolation). Fixes #992	2016-08-04 09:38:12 -07:00
Joe Lencioni	bfc842e3ad	Remove rules about reserved words In `53b4173b` we removed the ES5 guide which contains a lot of guidelines that are no longer very relevant for us. Similarly, some folks have raised the relevance of these rules about reserved words, given that we are now living in an age where ES3 support has mostly waned and transpilers such as Babel are widely adopted and pave over these issues. This seems like a good opportunity to simplify. Fixes #61	2016-08-03 14:41:16 -07:00
