javascript - An English string has a length of 1, occupies one byte, and each byte occupies 8 bits. How does js get the number of each bit in the memory?

Question

As the title states, this problem comes from the interaction with hardware

The hardware passes a character to the front end. The front end needs to obtain the 8 bits this character occupies in the memory, how many each bit is, and then make some specific responses,

Please give me full stack advice~~

Answer 1

var n = 100; // 4 + 32 + 64, 0110 0100
for (var i = 0; n != 0; n >>= 1)
{
    console.log(n & 1);
}

The result output from low to high is: 0 0 1 0 0 1 1
