Sort an array except one element in JavaScript

Question

I have an array and I am sorting it but I need to sort everything except one element of my array.

My array is:

var Comparison = [
    {key: \"None\", val         


        

Answer 1

A simple one-liner: if any of the keys in Array.prototype.sort compare function is 'None', then always put it on top, otherwise do basic comparison of keys with String.prototype.localeCompare():

var comparison = [{key: "None", value: "None"}, {key: "Geographical Area", value: "Geographical_Area"}, {key: "Forests", value: "Forests"}, {key: "Barren Unculturable Land", value: "Barren_Unculturable_Land"}, {key: "Land put to Non agricultural use", value: "Land_put_to_Non_agricultural_use"}, {key: "Land Area", value: "Land_Area"}, {key: "Water Area", value: "Water_Area"}, {key: "Culturable Waste", value: "Culturable_Waste"}, {key: "Permanent Pastures", value: "Permanent_Pastures"}, {key: "Land under Tree Crops", value: "Land_under_Tree_Crops"}, {key: "Fallow Land excl Current Fallow", value: "Fallow_Land_excl_Current_Fallow"}, {key: "Current Fallow", value: "Current_Fallow"}, {key: "Total Unculturable Land", value: "Total_Unculturable_Land"}, {key: "Net Sown Area", value: "Net_Sown_Area"}, {key: "Gross Sown Area", value: "Gross_Sown_Area"}, {key: "Cropping Intensity", value: "Cropping_Intensity"}];

var sorted = comparison.sort((a,b) => a.key === 'None' ? -1 : b.key === 'None' ? 1 : a.key.localeCompare(b.key));

console.log(sorted);
