JavaScript Assignment

JavaScript Assignment

Assignment operators assign values to variables. The basic one is =.

The = operator

let x = 10;

The value on the right is stored into the variable on the left.

Shorthand operators

JavaScript offers shortcuts that combine math with assignment:

Example

let score = 10;
score += 5;  // score is now 15
score -= 3;  // score is now 12
score *= 2;  // score is now 24

String assignment too

+= also works with strings:

let name = "Ada";
name += " Lovelace"; // "Ada Lovelace"

TL;DR

• = assigns a value.
• Shorthands like +=, -=, *=, /= combine math and assignment.
• += also concatenates strings.
