# Requires `for-of` statements instead of `Array#forEach` (prefer-for-of)
ES2015 introduced new `for-of` syntax.
It's more readable than `Array#forEach` since it does not require closures.
## Rule Details
:-1: Examples of **incorrect** code for this rule:
```js
/*eslint prefer-for-of: "error"*/
list.forEach(value => {
doSomething(value)
})
for (let i = 0; i < list.length; ++i) {
const value = list[i]
doSomething(value)
}
for (const i in list) {
if (obj.hasOwnProperty(i)) {
doSomething(obj[i])
}
}
for (const key in obj) {
doSomething(key, obj[key])
}
```
:+1: Examples of **correct** code for this rule:
```js
/*eslint prefer-for-of: "error"*/
for (const value of list) {
doSomething(value)
}
for (const key of Object.keys(obj)) {
doSomething(key, obj[key])
}
// Allow for indices.
list.forEach((value, index) => {
doSomething(index, value)
})
```
## Options
Nothing.
