Answer 1

let small = list[i].charAt(0).toUpperCase() + list[i].substring(1).toLowerCase();

This works ...

Answer 2

SoloProg Ipang thank you, but can you please explain me why my code was not working

Answer 3

let small= list[i].toLowerCase();
small = small.charAt(0).toUpperCase() + small.slice(1);

Answer 4

Assuming list[i] is "Russia"

let small = list[i].toLowerCase();
<small> = "russia"

let first=list[i].slice(0,1);
<first> = "R"

small = small.replace(first, first.toUpperCase());

Remember <first> = "R",
Replace all <first> in <small> by <first>.toUpperCase()

But <small> doesn't have 'R' in it, <small> = "russia", it has 'r' as first letter, so the replace() did nothing cause it didn't find any 'R' in <small>.

Answer 5

Ipang thanks, I did a little tweak to my code, instead for "let first=list[i].slice(0,1);" I did "let first=small.slice(0,1);"
