Specifically, the left-shift operator. It takes the left-hand argument and shifts the binary representation to the left by the number of bits specified by the right-hand argument, for example: 1 << 2 = 4 because 1 (decimal) is 1 (binary); left-shift twice makes it 100 which is 4 in decimal. 1 << 5 = 32
