JavaScript operators are used to assign values, compare values, perform arithmetic operations, and more.
Arithmetic operators are used to perform arithmetic operations between variables and/or values.
Assignment operators are used to assign values to JavaScript variables.
The + operator, and the += operator can also be used to concatenate (add) strings.
The conditional operator assigns a value to a variable based on a condition.
Logical operators are used to determine the logic between variables or values.
Bit operators work on 32 bits numbers. Any numeric operand in the operation is converted into a 32 bits.
The typeof operator returns the type of a variable, object, function or expression.
