should be better now

You don't need map if you don't need to create a new array. You can use .forEach if you just want to iterate through the array.

If you do it like that, won't it do the divison in every iteration? On top of that, it divides before adding ageSum.

What is the meaning of !String ? can you explain it?

i think it was from your early days of learning isn't it? i just explained to look documentation because i thought your are a beginner at coding.

don't call it as a solution 🤣

I want to find my own solution)

everything went smoothly until i saw this kata 😂 i used a brute force method and it didn't workout well. i'll bookmark this and come back after i learn JS better 😵

but only if it's one line if the arrow function consist of more than one line we need to explicitly write 'return' in our code.

clone the array before modifying it! this is the best practice 🙂

modifying a function's parameters with splice is not a good practice(because it's permanently change the original array). make a copy of the array and modify it 🙂

to be honest i got annoyed at first because the round is not working on some cases then got to know about num.toFixed(2) and it solved the issue. thank you for making me more stronger

if you just spent 10min on StackOverflow you don't have to write some code like this! do the research and you don't need to write code from the top of your head. refer documentation and use google when you are stuck! 🙂
