Hi Prashant,
I was able to solve this problem on my own thanks to your closure and function curry video.

Here is my solution.
const computeAmount = () => {
amount = 0

return {
crore: function(x){
amount +=
return this
},
lacs: function(x){
amount +=
return this
},
thousand: function(x){
amount += x*1000
return this
},
value: function(){
return amount
}
}
}


let total =

Thank you.

You can fast forward where you are writing repetitive code. Good video

Hello Prashant, Thank you for explaining with calmly and not rushing to get to the solution so fast.
I have one suggestion - please invest some amount to buy a good quality mic, it will help you to increase your engagement ratio and viewers will not get disturb, distracted while watching!

hi prashant, we can also be done it with function currying would be more easy and short any suggestions please

14:13 I didnt get the need of converting the solution to the function constructor? Can you elaborate please?
if we write computeAmount() and then chain it, its working fine, then why do we need function constructor?
