[milankbudha]

we can do
let add = function(num1, num2) {
return num1 + num2;
}
console.log(add(5, 6));//no need to create another result variable

Sir, waiting for this entire Javascript lecture series.

[yashesh]

by default undefined is assigned to any variable because javascript does not know beforehand what data type it is unless you have manually specified it

[AkankshaKothari-opxg]

It's really helpful for the beginner.

Sir it would really be halpful if u start a tutorial on Data science

[chisomchukwuma]

Thank you Sir for this tutorial, however, the idea of let variable being hoisted is wrong because if you did it this way( function greet(n){
console.log(user)
return `this is n ${n}`
}

let str=greet('me');
let user='Bounty'
console.log(str);) it won't work. Only 'var' declarations are hoisted to the global object

[guideline]

Let user = "admin" ---> global var

function add(num1, num2, num3)-->local var
{
return num1+num2+num3
let tech = "javascript"
}
let res = add(25+25+25)
console.log(add) -->execute
console.log(user) -->execute
console.log(tech) -->undefined

How to change value of a global variable inside function and then use changed value outside function.

[Martin]

Why does the function not explicitly return the value without the need for the return keyword?
