It does indeed perform a bit-wise NOT, the negative number is in two's complement. So the value 1010 is -6. Two's complement basically works by the very left-most bit signifies a negative number and is taken as a negative value. All other 1 bits are added to this number. For examp...
In JavaScript, the tilde~Bitwise NOT operatoris commonly used right before anindexOf()to do a boolean check (truthy/falsy) on a string. On its own,indexOf()returns the index number of a String object passed in. varfoo="bar";foo.indexOf("r");// 2foo.indexOf("b");// 0foo.index...
Bitwise XOR a ^ b Returns a one in each bit position for which the corresponding bits of either but not both operands are ones. Bitwise NOT ~ a Inverts the bits of its operand. Left shift a << b Shifts a in binary representation b (< 32) bits to the left, shifting in zeroes fro...
When bitwise NOT operation is performed, the binary result will be 11111111111111111111111111110011 which converts into the decimal value -13. Note: Bitwise NOT of a number x gives -(x + 1). Notice above ~2 gives -3. JavaScript Left shift In the left shift operator <<, the left operand ...

|= performs an in-place operation (原地运算符) between pairs of objects. In particular, between: sets: a union operation dicts: an update operation counters: a union (of multisets) operation numbers: a bitwise OR, binary operation In most cases, it is related to the | operator. See examp...
~ (Bitwise NOT) Performs the NOT operator on each bit. NOTayields the inverted value (a.k.a. one's complement) ofa. The truth table for the NOT operation is: 9 (base 10) = 00000000000000000000000000001001 (base 2) --- ~9 (base 10) = 11111111111111111111111111110110...
(0,1) representation of their arguments, rather than as decimal, hexadecimal, or octal numbers. For example, the decimal number eight has a binary representation of 1000. Bitwise operators do their operations on such binary representation (for example 1000) but they return standard JavaScript ...
Now, let's see if we get the correct answer or not. 35 = 00100011 (In Binary) // Using bitwise complement operator ~ 00100011 ___ 11011100 In the above example, we get that the bitwise complement of 00100011 (35) is 11011100. Here, if we convert the result into decimal we get 220...
