[javascript] <<= 연산자

15 Dec 2023

javascript

Here’s an example of how the <<= operator works:

let x = 5; // 00000000000000000000000000000101
x <<= 2;   // Shift left by 2 positions: 00000000000000000000000000010100
// Now x is 20

In this example, the value of x is first shifted to the left by 2 positions and then assigned back to x. As a result, the new value of x becomes 20.
