JavaScript Bitwise Operations - W3Schools
JavaScript Uses 32 bits Bitwise Operands. JavaScript stores numbers as 64 bits floating point numbers, but all bitwise operations are performed on 32 bits binary numbers. Before a bitwise operation is performed, JavaScript converts numbers to 32 bits signed integers. After the bitwise operation is performed, the result is converted back to 64 ...

Bit manipulation in JavaScript - GeeksforGeeks
Bit manipulation in JavaScript refers to the manipulation and operation of individual bits within binary representations of numbers and JavaScript uses 32-bit signed integers for numeric values. It involves using bitwise operators (&, |, ^, ~, <<, >>) to manipulate individual bits of binary numbers.

Bitwise AND (&) - JavaScript | MDN - MDN Web Docs
The & operator is overloaded for two types of operands: number and BigInt.For numbers, the operator returns a 32-bit integer. For BigInts, the operator returns a BigInt. It first coerces both operands to numeric values and tests the types of them. It performs BigInt AND if both operands become BigInts; otherwise, it converts both operands to 32-bit integers and performs number bitwise AND.

How to do bit manipulation in JavaScript - Coderslang: Become a ...
If both bits are the same - the result is 0. If the bits are different - the result is 1. ~ NOT: Inverts all bits in a number. << Left shift: Shifts all bits to the left, fills empty slots with zeros. >> Signed right shift: Shifts all bits to the right, fills empty slots with the leftmost bit, to maintain the sign of the number. >>> Unsigned ...

javascript - How to efficiently read bits out of bytes? - Stack Overflow
What I've come up with is converting all bytes into bits to a string using .toString(2), then using .substring to get a substring with length 3, and converting back to a number with parseInt(bitString, 2), but I guess that's not the way to do it, since string manipulation is slow and I'm actually not doing anything string-related.

Practical bit manipulation in JavaScript | by Joshua Parker - Medium
Real Booleans in JavaScript are not 1 bit, they are 32 bits or maybe 64. I don’t really know. But definitely not 1, but bits are (1 bit that is), so lets use them instead.

The Absolute Essentials for Bit Manipulation in JavaScript - Lucas F. Costa
Since bitwise operators deal with bits individually, this will change all bits except the third one. If the third bit was 0 it will remain as 0 and if it was 1 it will remain as 1, all other bits will become 0. Now we can simply shift the result 2 places to the right, which will then put the unchanged bit in the first place of our binary number.

Bit Manipulation in JavaScript: A Comprehensive Guide
Photo by Shahadat Rahman on Unsplash. Bit manipulation is a powerful technique used in computer science and programming to manipulate individual bits within binary data. In JavaScript, although it is not as commonly used as in lower-level languages like C or C++, it can still be quite valuable in certain scenarios, such as optimizing performance or working with binary data directly.
