In Javascript, call() and apply() are predefined methods. Both methods can be used to invoke a function & must have the owner object as first parameter. See More detail below:
apply lets you invoke the function with arguments as an array.
View 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 requires the parameters be listed explicitly one by one.
View Exmple:
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);
