Introduction

Arrow functions are a concise way of writing anonymous, lexically scoped functions in ECMAScript 2015 (ES6).

Syntax

=> x*2 // A line break before the arrow will throw a ‘Unexpected token’ error

x*2 // A line break after the arrow is a valid syntax

Remarks

For more information on functions in JavaScript, please view the Functions documentation.

Arrow functions are part of the ECMAScript 6 specification, so browser support may be limited. The following table shows the earliest browser versions that support arrow functions.
