The following is a function that takes a single number (digit) and then turns it in to a string (returned eg. 'one').
Refactor this code to be smaller and/or faster. It currently takes 700ms-800ms. You can use switch statements, inline ifs or anything else that you think could work (hint: arrays).
Happy coding!
function digitToText(digit) {
if (digit == 1) {
return 'one'
}
if (digit == 2) {
return 'two'
}
if (digit == 3) {
return 'three'
}
if (digit == 4) {
return 'four'
}
if (digit == 5) {
return 'five'
}
if (digit == 6) {
return 'six'
}
if (digit == 7) {
return 'seven'
}
if (digit == 8) {
return 'eight'
}
if (digit == 9) {
return 'nine'
}
if (digit == 0) {
return 'zero'
}
