Assignment Operator An assignment operator is the operator used to assign a new value to a variable. Assignment operator can also be used for logical operations such as bitwise logical operations or operations on integral operands and Boolean operands.
In JavaScript = is an assignment operator, which is used to assign a value to a variable. Often this operator is used to set a variable to a literal value, for example, var number1= ; var number2=number1; var name=”Computer Science”; var booleanvar=true; The assignment operator is used to assign a value to a single variable, but it is possible to perform multiple assignments at once by stringing them together with the = operator. For example, the statement Chapter Pages var m = n = z = ; // sets all three variables to a value of // The assignment operator can also be used to set a variable to hold the value of an expression. For example, var x = + - ; // x set to // JavaScript supports some shorthand arithmetic operators like +=, -=, *=, /= and %= to evaluate arithmetic calculations.
