trying to convert a letter to uppercase using .toUpperCase()… doesn't work?

Question

I\'m trying to convert a character in an array to uppercase using .toUpperCase(), but it doesn\'t work. I\'m pretty sure my logic is correct, so not sure why it\'s not working?<

Answer 1

console.log(tempArr[i]); //this will display "i" and "p".. why?

because you were not storing the converted value back to the variable

make it

tempArr[i] = tempArr[i].toUpperCase();
