              Unary Negation Operator (-) in JavaScript

              JavaScript’s unary negation operator negates the current sign of a number. The symbol of the unary negation operator in JavaScript is -.

              Example:

              var numberone=-3;

                Decrement Operator (–) in JavaScript

                The decrement operator is used to subtract 1 from the operand. It can be placed before and after the operand. The symbol of decrement operator in JavaScript is –.

                Decrement Operator before the Operand

                Example:

                var numberone=3;
                var theresultof=--numberone;
                window.alert (theresultof);

                  Increment Operator (++) in JavaScript

                  JavaScript’s increment operator can be use in front of the operand (the value on it operates) or after operand. It increases the value of the operand by 1 and the result depends on what side of the operand it is placed. The symbol of increment operator in JavaScript is ++.

                  Increment Operator before the operand

                  Example:

                  var numberone=2;
                  var theresultof=++numberone;
                  window.alert (theresultof);

                    Modulus Operator in JavaScript

                    JavaScript’s modulus operator is used to calculate the value of the integer remainder of a division. If you calculate 5 divided by 2 the result will be something like you learned in school, to give the result with reminders rather than transform it in decimals. The symbol of modulus operator in JavaScript is %.

                    Example:
                    Calculate the modulus of 5 divided by 2

                    var numberone=5;
                    var numbertwo=2;
                    var theresultof=numberone%numbertwo;
                    window.alert (theresultof);

                      Division Operator in JavaScript

                      JavaScript’s division operator is used to divide the value on the left side by the value on the right side just like mathematical division learned in school. The symbol of division operator is /.

                      Example:
                      Calculate 3 divided by 2

                      var numberone=3;
                      var numbertwo=2;
                      var theresultof=numberone/numbertwo;
                      window.alert (theresultof);
