Bit manipulation is an advanced topic that JavaScript developers typically do not need to know. Low-level programming languages such as C take advantage of these operators. However, you should learn a bit about bit manipulation if you want to implement high-performance server-side code.

Understanding bit manipulation requires some knowledge of digital logic. Any introductory course in discrete math or circuits would be helpful to understand these concepts.

Bitwise Operators

Here are the bitwise operators in JavaScript:

  • & :   AND

  • | :   OR

  • ~ :   NOT

  • ^ :   XOR

  • <<:   Left shift
