eslint-plugin-no-for-of-loops

Prevents for (...of) loops usage in your code base.

Installation

npm install --save-dev eslint-plugin-no-for-of-loops

Usage

In your .eslintrc:

{
  "plugins": [
    "no-for-of-loops"
  ],
  "rules": {
    "no-for-of-loops/no-for-of-loops": 2
  }
}

Rule

Disallow use of for (..of) loops.

Why

Using for (...of) loops requires a Symbol and iterator polyfill to work on older browsers (see babel/babel#1534) Depending on your browsers target (for example, Android 4.4 in-app Webview is capped to Chrome 33), you might not want to include those polyfills to save some kilobytes.

See for..of and Symbol compatibily tables

Disabling the rule

What to disable the rule anyway? Your call :

// eslint-disable-next-line no-for-of-loops/no-for-of-loops
for (let i of iterable) {
  // ...
}
