Question

What does somevar >> 0javascript mean ?

thank

Answer 1

B a >> b, >>is a bitwise operator that shifts bits ain the binary representation b(<32) to the right, discarding bits shifted. Link: https://developer.mozilla.org/en/JavaScript/Reference/Operators/Bitwise_Operators

Answer 2

Bit shift to the right . Although somevar >> 0it looks strange.

Answer 3

This is a bitwise operator. In this case, to offset the first operand in binary representation, the number of bits to the right specified in the second operand, the discarding of the bits is shifted.

With 0as the second operand, I think it has no effect (offset 0 bits, get the same value?).

I made a mistake with this last one. As explained in this comment by @Gumbo .
