Although not a commonly used operator, the **bitwise operator** is essential to keep in mind that this operator handles the operand inside the variable as its **32-bit** machine language. Although it's operating under binary digits, the output is displayed in decimal.

## 1. Bitwise AND (&)

Bitwise **AND **and **&&** from the logical operator are two separate things that cannot be confused with one another. Here the operator gives out 1 if both the operand bits are 1. Else, it gives out 0.

So basically.

```
0 and 0 is equal to 0
0 and 1 is equal to 0
1 and 0 is equal to 0
1 and 1 is equal to 1
```

### Example:

```
let x = 15;
let y = 26;
finalOut = x & y
console.log(finalOut)
```

**Output: **10

```
00001111
00011010
--------
00001010 => 10
```

- The binary value of 15 is 00001111.
- And 26 is 00011010.
- So 00001010 is 10 in decimal.
- Turns out the final output, as discussed, has given out the decimal value.

## 2. Bitwise OR (|)

If either of both sides of an operand consists of 1, the bit gives out 1. Else it gives out 0.

```
0 and 0 is equal to 0
0 and 1 is equal to 1
1 and 0 is equal to 1
1 and 1 is equal to 1
```

### Example:

```
let x = 15;
let y = 26;
finalOut = x | y
console.log(finalOut)
```

**Output: **31

```
00001111
00011010
--------
00011111 => 31
```

## 3. Bitwise XOR (^)

This one gives out 0 if both operand's bits are the same and gives out 1 if it is different.

```
0 and 0 is equal to 0
0 and 1 is equal to 1
1 and 0 is equal to 1
1 and 1 is equal to 0
```

### Example:

```
let x = 15;
let y = 26;
finalOut = x ^ y
console.log(finalOut)
```

**Output: **21

```
00001111
00011010
--------
00010101 => 21
```

## 4. Bitwise NOT (~)

The NOT Operator inverts the operand bits opposite to its corresponding bit.

`00001111 in NOT turns to 11110000`

### Example:

```
let x = 15;
finalOut = ~x
console.log(finalOut)
```

**Output: **-16

- While converting 00001111 to 11110000, it gives out 240.
- The value is then computed to decimal signed 2's complement.
- 2's complement is nothing, but after the inversion, it gets added with 1.

```
11110000
1
---------
11110001 => -16
```

## 5. Bitwise Left Shift (<<)

- The left shift operator shifts the left operand specified from right to left. It adds zeros. The number of zeros depends upon the right operand.
- So 15 is 00001111 shifting left with 26 gives out 00001111, 00000000000000000000000000 which is in decimal value 1006632960.

### Example:

```
let x = 15;
let y = 26;
finalOut = x << y
console.log(finalOut)
```

**Output: **1006632960

## 6. Bitwise Right Shift (>>)

- In the right shift, the operator removes the last bits of the first operand from the right side.
- So again, 15 is 00001111. Doing a right shift with, say 2, removes the last two bits 000011, which in decimal value is 3.

```
let x = 15;
let y = 2;
finalOut = x >> y
console.log(finalOut)
```

**Output: **3

So likewise **>>>** and **>>** are both similar to what they do by pushing from left to right and removing the last right side bits by the specified operand.
