call() and apply() are two predefined javascript methods. We use both of them to invoke a function & these method must have its own object as a first parameter.

apply allow us to invoke the function with passing the arguments in the form of array.

Example:

function myFunction1(a, b) {
            return a + b;
        }
        var myobj1 = new Object();
        var result1 = myFunction1.call(myobj1, 5, 6);
        console.log('Result with call function: ' + result1);

call always requires that all parameters will be listed explicitly not implicitly and one by one.

Example:

function myFunction2(a, b) {
            return a + b;
        }
        myArray = [5, 6];
        var myobj2 = new Object();
         var result2 = myFunction2.apply(myobj2, myArray);   
         console.log('Result with Apply function: ' + result2);
