An assignment operator requires two operands. The value of the right operand is assigned to the left operand. The sign = denotes the simple assignment operator. The typescript also has several compound assignment operators, which is actually shorthand for other operators. List of all such operators are listed below

List of Assignment operators
| Name | Syntax | Meaning |
|---|---|---|
| Assignment | x = y | x = y |
| Addition assignment | x += y | x =x+ y |
| Subtraction assignment | x -= y | x = x - y |
| Multiplication assignment | x *= y | x = x * y |
| Division assignment | x /= y | x = x / y |
| Remainder assignment | x %= y | x = x % y |
| Exponentiation assignment | x **= y | x = x ** y |
| Left shift assignment | x <<= y | x = x << y |
| Right shift assignment | x >>= y | x = x >> y |
| Unsigned right shift assignment | x >>>= y | x = x >>> y |
| Bitwise AND assignment | x &= y | x = x & y |
| Bitwise XOR assignment | x ^= y | x = x ^ y |
| Bitwise OR assignment | x |= y | x = x | y |
| Logical AND assignment | x &&= y | x && (x = y) |
| Logical OR assignment | x ||= y | x || (x = y) |
| Logical nullish assignment | x ??= y | x ?? (x = y) |
Simple Assignement Operator
The = assignment operator assigns the value of the right hand operand to the left hand variable.
1 2 3 4 5 6 7 | var x = 25; var y = 25*100; var z = x+y; |
Compound Assignment Operators
All operators except = listed in the table above are compound assignment operators. They are actually short hand notations
For Examples
The Addition assignment += operator adds a value to a variable.
1 2 3 4 | var x = 25; x +=25; //50; |
is actually short hand for
1 2 3 4 | var x= 25; x = x + 25; //50 |
