function solution(s) {
    let numbers = ["zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine"];
    var answer = s;

    for(let i=0; i< numbers.length; i++) {
        let arr = answer.split(numbers[i]);
        answer = arr.join(i);
        console.log("arr", arr);
        console.log("answer", answer);
    }

    return Number(answer);
}

arr [ 'one4seveneight' ]
answer one4seveneight
arr [ '', '4seveneight' ]
answer 14seveneight
arr [ '14seveneight' ]
answer 14seveneight
arr [ '14seveneight' ]
answer 14seveneight
arr [ '14seveneight' ]
answer 14seveneight
arr [ '14seveneight' ]
answer 14seveneight
arr [ '14seveneight' ]
answer 14seveneight
arr [ '14', 'eight' ]
answer 147eight
arr [ '147', '' ]
answer 1478
arr [ '1478' ]
answer 1478
