In-Depth Information
position for which the corresponding bits of either operands are 1s, but not both
1
s. Here's
an example:
12 ^ 10; // in binary this is 1100 & 1010, so only the
second and
↵
third digits are exclusively 1s
<< 6
When using non-integer values, this evaluates to
1
if
either
operands are truthy and evalu-
ates to
0
if both operands are truthy or both are falsy:
1 ^ 0; // The first operand is truthy
<< 1
true ^ true; // if both operands are true then the result
is false
<< 0
Bitwise Shift Operators
The bitwise shift operators,
<<
and >>, will move the binary representation a given number
of places to the right or left, which effectively multiplies or divides the number by powers
of two:
3 << 1; // multiply by 2
<< 6
16 >> 1; // divide by 2
<< 8
5 << 3; multiply by 2 cubed (8)
<< 40
