What is operator in node JS?
Comparison operators
| Operator | Description |
|---|---|
| Equal ( == ) | Returns true if the operands are equal. |
| Not equal ( != ) | Returns true if the operands are not equal. |
| Strict equal ( === ) | Returns true if the operands are equal and of the same type. See also Object.is and sameness in JS. |
Is ++ a compound operator?
Compound expressions and conditional expressions are lvalues in C++, which allows them to be a left operand in a compound assignment expression….Compound assignment operators.
| Operator | Left operand | Right operand |
|---|---|---|
| += or -= | Pointer | Integral type |
| *=, /=, and %= | Arithmetic | Arithmetic |
| <<=, >>=, &=, ^=, and |= | Integral type | Integral type |
What are compound operators?
The compound assignment operators consist of a binary operator and the simple assignment operator. They perform the operation of the binary operator on both operands and store the result of that operation into the left operand, which must be a modifiable lvalue.

Compound assignment operators Operator Example Equivalent expression += index += 2 index = index + 2 -= * (pointer++) -= 1 *pointer = * (pointer++) – 1 *= bonus *= increase bonus = bonus * increase /= time /= hours time = time / hours
Is it possible to type-cast compound assignment operators?
But in the case of compound assignment operators internally type-casting will be performed automatically, even we are assigning a bigger value to a smaller data-type variable but there may be a chance of loss of data information. The programmer will not responsible to perform explicit type-casting.
