I have an array like this
["1","0K","11",1,"KE","PQ",5,"5"]
where i want it to sort first by text then by number like below
["KE","PQ","0K","1",1,5,"5","11"]
I used local compare but it didn't seem to be working.
function desc(a,b){
//below is the code that needs improvement
return b.toString().localeCompare(a, undefined, {
numeric: true,
sensitivity: "base",
});
}
function sort(order) {
return order === "desc"
? (a, b) => desc(a, b)
: (a, b) => -desc(a, b);
}
function stableSort(array, cmp){
const stabilizedThis = array.map((el, index) => [el, index]);
stabilizedThis.sort((a, b) => {
const order = cmp(a[0], b[0]);
if (order !== 0) return order;
return (a[1]) - (b[1]);
});
return stabilizedThis.map((el) => el[0]);
}
var arr = ["1","0K","11",1,"KE","PQ",5,"5"];
console.log(stableSort(arr, sort("asc"))) var arr = ["1","OK","11",1,"KE","PQ",5,"5"]
var wordArr = []
var numArr = []
arr.forEach((el) => {
if(Number(el)){
numArr.push(el)
} else {
wordArr.push(el)
}
});
wordArr.sort()
numArr.sort((a, b) => a - b)
arr = wordArr.concat(numArr)
console.log(arr)
You could write filter methods to get the strings containing numbers, remove the entries, get numbers and strings separately from rest and then sort them in the way you like.
const data = ["1","0K","11",1,"KE","PQ",5,"5"];
const stringsWithNumbers = data.filter(x => /\d+[a-zA-Z]/.test(x));
const rest = data.filter(x => !stringsWithNumbers.includes(x));
const numbers = rest.filter((x) => parseInt(x, 10));
const words = rest.filter((x) => !parseInt(x, 10));
const result = [
...words.sort((a, b) => a.localeCompare(b)),
...stringsWithNumbers.concat(numbers).sort((a, b) => parseInt(a) - parseInt(b)),
];
console.log(result);const sort = (arr = []) => {
const nonAlpha = /[^a-zA-Z]/g, nonNum = /[^0-9]/g;
return arr.sort((a, b) => {
const aStr = String(a), bStr = String(b);
const aAlpha = aStr.replace(nonAlpha, ""), bAlpha = bStr.replace(nonAlpha, "");
const alphaCompare = bAlpha.localeCompare(aAlpha);
if(alphaCompare) return alphaCompare;
const aNum = +aStr.replace(nonNum, ""), bNum = +bStr.replace(nonNum, "");
return aNum - bNum;
});
}
console.log( sort(["1","0K","11",1,"KE","PQ",5,"5"]) );
