JavaScript Operators

Example

Assign values to variables and add them together:

var x = 5;         // assign the value 5 to x

var y = 2;         // assign the value 2 to y

var z = x + y;     // assign the value 7 to z (x + y)

The assignment operator (=) assigns a value to a variable.

Assignment

var x = 10;

The addition operator (+) adds numbers:

Adding

var x = 5;

var y = 2;

var z = x + y;

The multiplication operator (*) multiplies numbers.

Multiplying

var x = 5;

var y = 2;

var z = x * y;
