Typescript operators: Learn bitwise, assignment, and comma operators with examples.
Typescript Bitwise operators
Bitwise operators are used to evaluating bit-based operations.
Sometimes, it is required to evaluate bits of integer values, We have to use bitwise operators.
There are several operators like in many programming languages. It works with 32 bits of an integer.
These operators work on binary operands.
Syntax:
Operand1 Operator Operand2
Operand1 and Operand2 are javascript expressions. Operators are bitwise operators.
Let’s assume that the value of A and B are 5 and 10, and the result is as follows.
| Operator | Title | Description | Example |
|---|---|---|---|
| & | Bitwise AND | Evaluates And operation on bits Integers parameters | A & B is 0 |
| | | Bitwise OR | Evaluates Or operation on bits Integers parameters | A | B is 15 |
| ^ | Bitwise XOR | Evaluates exclusive operation on bits of Integers parameters | A ^ B is 15 |
| ~ | Bitwise NOT | Not operator on bits of parameter | ~A is -6 |
| « | Left Shifts | First shifts left bits of the first operand by second operand times and the remaining bits will be filled with zero | A« |
| >> | Right Shifts | First shifts right bits of the first operand by second operand times and the remaining bits will be filled with zero | A»B is 0 |
| >» | Right Shifts with zero | Evaluation is right shift + left Bits shifted replaced with zero | A»>B is 0 |
Following is a Bitwise operators Example.
var A = 5
var B = 10
console.log(A & B) // returns 0
console.log(A | B) // returns 15
console.log(~A) // returns -6
console.log(A^B) // returns 15
console.log(A<**>B) // returns 0
console.log(A>>>B) // returns 0
Typescript Assignment Operators
Assignment operators do some operations and assign the value from left to right values.
Syntax:
Operand1 Assignment-operator Operand2
The following table explains it with examples.
| Operator | Title | Description | Example |
|---|---|---|---|
| = | Simple assign | Evaluates, And operation on bits Integers parameters | a=2 and value of a is 2 |
| += | Add And assign | Add right operand to left and assign the result to left operand | a+=2 and value of a is equal to a=a+2 |
| -= | Subtract and assign | Subtract right operand to left and assign the result to left operand | a-=2 and value of a is equal to a=a+2 |
| *= | Multiply And assign | Multiply right operand with left and assign the result to left operand | a*a=2 is equal to a=a*2 |
| /= | Divide and assign | Divide right operand with left and assign the result to left operand | c/=2 is equal to c=c/2 |
| %= | Modulus And Assign | Divide right operand with left and assign the result of the remainder to left operand | c%=2 is equal to c=c%2 |
| «= | Left Shifts And assign | Perform left shift and result is assigned to left operand | c«=2 is equal to c=c«2 td=""> |
| >>= | Right Shifts And assign | Perform Right shift and result is assigned to left operand | c»=2 is equal to c=c»2 |
| &= | Bitwise And Assign | Perform Bitwise And and the result is assigned to left operand | c&=2 is equal to c=c&2 |
| ^= | Bitwise Exclusive And Assign | Perform Bitwise Exclusive OR and result is assigned to left operand | c^=2 is equal to c=c^2 |
| |= | Bitwise Or And Assign | Perform Bitwise inclusive OR and the result is assigned to left operand | c|=2 is equal to c=c|2 |
Typescript Comma Operator
This operator symbol is a comma(,).
This is used to perform the multiple expressions and return the last expression value.
Multiple expression is evaluated from left to right.
Syntax :-
(Operand/Expression,Operand2)
Here is an example Example
var variable =10;
variable = (--variable, variable);
console.log(variable); // outputs 9
Conclusion
To summarize, you learned about typescript operators with examples.
- Bitwise operator
- Comma operator
- Assignment operator
