Tried it on my own, it was so easy.. but I just need to practice more often with different examples.. I really start enjoying JS as a beginner with your friendly good explanation.. I need more of these tips

[uchennachukwuba]

The callback function should have been omitted because it's just logging the same message in the set timeout function. May be it was used just for explanatory purpose

loved your videos sir... i have an doubt on call back...

let arr = [1, 2, 3, 4, 5];
let fil = function (ele){return ele > 2}
let p = arr.filter(fil)
let k = arr.filter(function(){fil()})
console.log(p)
console.log(k)

sir why this k gives empty array .. both p and k are func refrence right?

in my VS code, variable num is printed as it is.. value of 2 is not passing though it.

function foo(num) {
console.log('foo ${num}');
}
foo(2);


console output: foo ${num}

what am I doing wrong?

[worldbest]

im just curious that, i can't understand the difference between just use console.log in orderpizza function and callback function in orderpizza function. whta does it mean by that Robin's phone didn't get message?

Hi Tapas,
In your video you showing about chrome console within your VSCode Editor.
I've tried that console.log but no success.
Could you show me how to activate that console.

Thanks.
