Iterate through each char in the string ransomNote. If you can find the char in the string tempMagazine, remove the char from tempMagazine (indicating that the char has been used by ransomNote). Return false if you cannot find the char in tempMagazine.

function canConstruct(ransomNote: string, magazine: string): boolean {

    let char = '';
    let tempMagazine = magazine;
    for(let i =0; i< ransomNote.length; i+= 1){
        char = ransomNote.charAt(i);

        if(tempMagazine.indexOf(char) > -1) tempMagazine = tempMagazine.replace(char, '');
        else return false;
    }
    return true;
};
