JavaScript assignment operators are used to assign the values to the operands.
JavaScript Assignment Operators List:
| Operator | Description | Example |
| = | Assign | a = 10 + 10; Result into a = 20 |
| += | Add and assign | var a=10; a+=20; Result into a = 30 |
| -= | Subtract and assign | var a=20; a+=10; Result into a = 10 |
| *= | Multiply and assign | var a=10; a*=20; Result into a = 200 |
| /= | Divide and assign | var a=10; a/=2; Result into a = 5 |
| Modulus and assign | var a=10; |
JavaScript Assignment Operators Example:
<html>
<head>
<script type="text/javascript">
var a = 33;
var b = 10;
var linebreak = "<br />";
document.write("Value of a => (a = b) => ");
result = (a = b);
document.write(result);
document.write(linebreak);
document.write("Value of a => (a += b) => ");
result = (a += b);
document.write(result);
document.write(linebreak);
document.write("Value of a => (a -= b) => ");
result = (a -= b);
document.write(result);
document.write(linebreak);
document.write("Value of a => (a *= b) => ");
result = (a *= b);
document.write(result);
document.write(linebreak);
document.write("Value of a => (a /= b) => ");
result = (a /= b);
document.write(result);
document.write(linebreak);
document.write("Value of a => (a
result = (a
