Vowels letters in upper case

Question

Morning guys!

I need the vowels letters in upper case.

I've tried this but doesn't work:

let arr = ['1 abcde', '2 abcde', '3 abcde'];
let vowels = ['a','e','i','o','u'];
let list = [];

for(let item in arr){
    if(item in vogals){
    list.push(item.toUpperCase());
    }else{
    list.push(item.toLowerCase());
    }
}

I want this result:

//Expected result: 
arr = ['1 AbCdE', '2 AbCdE', '3 AbCdE']

Help me please!

That's not your actual code, presumably. Please post the actual code. And explain what error(s) you are seeing. — jarmod, Sep 07 '22 at 14:58
`if(item in vogals){` - What is `vogals`? Did you mean `vowels`? — Tim Lewis, Sep 07 '22 at 14:58

`if(item in vogals)` Lets assume the first item `if ('1 abcde' in vowels)` No, that's not going to work. — Keith, Sep 07 '22 at 15:00
You have an incredible amount of errors. You may find it beneficial to review the fundamentals again first. — CertainPerformance, Sep 07 '22 at 15:00

It should be probably something like this:

let arr = ['1 abcde', '2 abcde', '3 abcde'];
let vowels = ['a','e','i','o','u'];
const result = arr.map(str => [...str].map(char => vowels.includes(char) ? char.toUpperCase() : char).join(''))
console.log(result)
