Shift Operator in Java - GeeksforGeeks
WebJun 20, 2024 · The bitwise left-shift operator (<<) in JavaScript allows you to shift all bits in a number to the left. It achieves this by appending zeroes to the end of the number. Any excess bit on the left side is dropped off during the shifting process. Two less-than signs represent the left shift operator. The left operand is the variable you want to shift. WebDec 25, 2024 · This causes only the 32nd bit (the leftmost bit) to be discarded when shifting.
