In this topic, we will discuss Assignment Operators Examples in Typescript.
| Operator | Description | Example |
|---|---|---|
| = (Simple Assignment) | Assigns values from the right side operand to the left side operand | C = A + B will assign the value of A + B into C |
| += (Add and Assignment) | It adds the right operand to the left operand and assigns the result to the left operand. | C += A is equivalent to C = C + A |
| -= (Subtract and Assignment) | It subtracts the right operand from the left operand and assigns the result to the left operand. | C -= A is equivalent to C = C – A |
| *= (Multiply and Assignment) | It multiplies the right operand with the left operand and assigns the result to the left operand. | C *= A is equivalent to C = C * A |
| /= (Divide and Assignment) | It divides the left operand with the right operand and assigns the result to the left operand. |
Note − Same logic applies to Bitwise operators, so they will become <<=, >>=, >>=, &=, |= and ^=.
Example
var a: number = 12
var b:number = 10
a = b
console.log("a = b: "+a)
a += b
console.log("a+=b: "+a)
a -= b
console.log("a-=b: "+a)
a *= b
console.log("a*=b: "+a)
a /= b
console.log("a/=b: "+a)
a %= b
console.log("a%=b: "+a)
On compiling, it will generate the following JavaScript code −
var a = 12;
var b = 10;
a = b;
console.log("a=b: " + a);
a += b;
console.log("a+=b: " + a);
a -= b;
console.log("a-=b: " + a);
a *= b;
console.log("a*=b: " + a);
a /= b;
console.log("a/=b: " + a);
a %= b;
console.log("a%=b: " + a);
It will produce the following output −
a = b: 10 a += b: 20 a -= b: 10 a *= b: 100 a /= b: 10 a %= b: 0
