Javascript :: toString and parseFloat

TostringAndParsefloat1.js

const zeroDarkThirty = (aNum) => {
    const stringNum = aNum.toString();
    let zerolessString = '';
    
    for (let i = 0; i < stringNum.length; ++i) {
        const currentDigit = stringNum[i];
        
        if (currentDigit !== '0') zerolessString += currentDigit;
    } return parseFloat(zerolessString);
}

// this takes a number and gets rid of the zeroes, and returns the zeroless number.
// parseFloat returns number with decimal places
// parseInt would return integer
