How to get prime factors in JavaScript

Let's assume that you want to get the prime factors of a number n in JavaScript:

javascript
let getPrimeFactors = (n) => {

    let factors = { '1': true }

    for(let i = 2; i <= n; i ++){

        while(n % i === 0){

            factors[i] = true
            n = n / i

        }
        
    }

    return Object.keys(factors)

}

For example, let's do it step by step for n = 10.

terminal
# We divide by 2 until the remainder is different from zero
# That will prevent that 4, 8, 10 are added as factors
i = 2
10 % 2 = 0
factors[2] = true
n = 10 / 2 = 5
5 % 2 = 3

# We divide by 3 until the remainder is different from zero
# That will prevent that 6, 9 are added as factors
i = 3
5 % 3 = 2

i = 4
5 % 4 = 1

i = 5
5 % 5 = 0
factors[5] = true
n = 5 / 5 = 1
