Devi's solution to sort

sort_array.js

function sortBy(arr, fn= ()=>{}) {
    const array = [...arr];
    for (let i=0; i<array.length; i++) {
        for (let j=i+1;j<array.length;j++){
        if (array[j] < array[i]) {
            const temp = array[i];
            array[i] = array[j];
            array[j] = temp;
        }
    }
    }
    return array;
};

const rr = sortBy([34,12,67,1,2,9,5,3], (x)=>x);
console.log(rr)
