                                                                                                 (a=3)
                   *=     Multiplication  It multiplies right operand with the left operand and assigns   a *= 3  9
                          assignment    the result to left operand. x*=3 is equivalent to x=x*3.
                   /=     Division      It divides left operand with the right operand and assigns   a /= 3     1
                          assignment    the result to left operand. x/=3 is equivalent to x=x/3.
                  %=      Remainder     It takes modulus of two operands and assigns the result to   a %= 3     0
                          assignment    left operand. x%=3 is equivalent to x=x%3.
                  **=     Exponent      It raises the value of a variable to the power of the right   a **= 3   27
                          assignment    operand. x = x**=3

                 Complete the following activity and tick on the circle.
                 1.  Create JavaScript programs to calculate the following and display the result with
                   appropriate messages:
                      Area and perimeter of a rectangular lawn
                      Simple Interest
                 2. Try the following code snippets and check the output:
                      document.write( “WELCOME” + “TO” + “ALL”)
                      document.write (10+12+ “234”)


              Comparison Operators
              To determine equality or difference between variables or values, comparison operators are utilised in logical
              statements.
