JavaScript Spread Syntax Explained

Thu, 03 Mar 2022 21:28:27 -0600

JavaScript’s spread syntax, ..., lets you expand one value into another context. It is small, useful, and easy to misunderstand.

The practical version is this:

In an array literal, spread adds values from an iterable.
In a function call, spread passes values from an iterable as separate arguments.
In an object literal, spread copies an object’s own enumerable properties.

Spread expands a source into the place where you use it.
