JavaScript Tutorial in Hindi part 11: Function in JavaScript in Hindi | JavaScript Functions

Welcome All, we will see function in javascript in hindi. A JavaScript function is a block of code designed to perform a particular task.

A JavaScript function is executed when "something" invokes it (calls it).

JavaScript Function Syntax
A JavaScript function is defined with the function keyword, followed by a name, followed by parentheses ().

Function names can contain letters, digits, underscores, and dollar signs (same rules as variables).

The parentheses may include parameter names separated by commas:
(parameter1, parameter2, ...)

The code to be executed, by the function, is placed inside curly brackets: {}

[bijaylama]

function subtotal(math, eng, sc, hi, sans){
var total = math + eng + sc + hi + sans;
return total;
}
function percentage(total) {
var per = total/500 * 100;
document.write(per);
}
var result =subtotal(63, 84, 32, 65, 45);
percentage(result)
. in this code i want to know is the total from subtotal function same total which is used in the percentage funciton if thats the case it makes sense the subtotal is returning a value total and the percentage fucntion is using it in its parameter MY QUESTION IS WHY AND HOW ...OR WHAT IS IT CALLED BECAUSE BOTH FUNCTION HAVE DIFFERENT SCOPES... Sir I need your Gudience....please
