Bitwise Operators
Bitwise operators work with operands that are 32-bit integers. These are numbers written in
binary (base two) that have 32 digits made up of just 0 s and 1 s. Here are some examples:
5 is written as 00000000000000000000000000000101
100 is written as 00000000000000000000000001100100
15 is written as 00000000000000000000000000001111
JavaScript will convert any values used with bitwise operators into a 32-bit integer and then
carry out the operation.
Bitwise NOT
The bitwise NOT operator [ ~] will convert the number to a 32-bit integer, then change all
the 1 s to 0 and all the 0 s to 1 s. For example, 2476 can be represented as:
Which will change to:
This is 1073736019, but the result actually uses negative values, as you can see in the code:
<< -45
In most cases, this operator will return an integer that adds to the original operand to make
