How would I display positive number such as 3 as +3 and negative numbers such -5 as -5? So, as follows:

1, 2, 3 goes into +1, +2, +3

but if those are

<

Answer 1

// Forces signing on a number, returned as a string
function getNumber(theNumber)
{
    if(theNumber > 0){
        return "+" + theNumber;
    }else{
        return theNumber.toString();
    }
}

This will do it for you.

Answer 2

Even though using ternary operator is arguably more practical, here's another interesting way of doing this:

'+'.repeat(number >= 0) + number

or this:

[['+'][number & 0x80000000], number].join('')

Answer 3

['','+'][+(num > 0)] + num

or

['','+'][Number(num > 0)] + num

It is a shorter form than the ternary operator, based on casting boolean to the number 0 or 1 and using it as an index of an array with prefixes, for a number greater than 0 the prefix '+' is used
