Function in JS

A JavaScript function is a block of code designed to perform a particular task.

Why did Function need?

You can reuse code: Define the code once, and use it many times.

• How can we declare a function
• Parameterize Function
• Return the value from a function
• The function can be assign to a variable

Example Code:

function printData(numbr){
var num= numbr;
var name = "Rohit";

if(num > 300){
return 'Number is more than 300';
}else{

return 'Number is less than 300';
}
}


var p1 = printData(200);

var p2 = printData(301);

gs.info(p1 + p2);
