# JavaScript: Bitwise Operators

## Bitwise Operators

Bitwise operators perform an operation on the bitwise (0,1) representation of their arguments, rather than as decimal, hexadecimal, or octal numbers. For example, the decimal number eight has a binary representation of 1000. Bitwise operators do their operations on such binary representation (for example 1000) but they return standard JavaScript numerical values.

Here is a list of JavaScript's bitwise operators.

Operator |
Usage |
Description |
---|---|---|

Bitwise AND | a & b | Returns a one in each bit position if bits of both left and right operands are ones. |

Bitwise OR | a | b | Returns a one in each bit if bits of either left or right operand is one. |

Bitwise XOR | a ^ b | Returns a one in a bit position if bits of one but not both left and right operand are one. |

Bitwise NOT | ~ a | Flips the bits of its operand. |

Left shift | a << b | Shifts a in binary representation b bits to the left, shifting in zeros from the right. |

Sign-propagating right shift | a >> b | Shifts a in binary representation b bits to the right, discarding bits shifted off. |

Zero-fill right shift | a >>> b | Shifts a in binary representation b bits to the right, discarding bits shifted off, and shifting in zeros from the left. |

**Add padding to the beginning of a string**

const name = 'Minta Lofton'; console.log(name.padStart(13)); console.log(name.padStart(2));

With the padStart method, we can add padding to the beginning of a string. The value passed to this method is the total length of the string together with the padding. The string "Minta Lofton" has a length of 12. name.padStart(13) inserts 1 space at the start of the string, because 12 + 1 is 13.

If the argument passed to the padStart method is smaller than the length of the array, no padding will be added.
