I am trying to sort an array of strings based on a character inside each of those strings. So far, I have this
function doMath(s) {
let arr = s.split(' ');
let letterArr = [];
let sortedArr = [];
let n = 0;
for (var i = 0; i < arr.length; i++) {
n = arr[i].indexOf(arr[i].match(/[a-z]/i));
letterArr.push(arr[i][n]);
}
letterArr.sort();
console.log(letterArr);
for (i = 0; i < arr.length; i++) {
for (var j = 0; j <= arr[i].length; j++) {
if (arr[i].indexOf(letterArr[j]) > -1) {
sortedArr.unshift(arr[i]);
}
}
}
console.log(sortedArr);
}
doMath("24z6 1x23 y369 89a 900b");
The problem is shown when I log this array. If I use sortedArr.push(arr[i]);
,
then the output is:
["24z6", "1x23", "y369", "89a", "900b"]
However, when I use sortedArr.unshift(arr[i]);
, I get the output:
["900b", "89a", "y369", "1x23", "24z6"]
I am not sure why the b
comes before the a
.
I just want it to be a-z for the sorting. I tried push()
and it is correct but backwards (z-a). When I try unshift()
, it's correct except the b
and a
are switched.
