Searching many examples I didn't manage to solve my case. I have an array that should be sorted by author. My attempt did nothing. What is the right expression?
var array = [ ["ifke", { "title": "secure", "author": "admin" }], ["lottery", { "title": "The lo", "author": "anton" }], ["short-content", { "title": "Short Content", "author": "scott" }], ["ziddler", { "title": "The Fiddler", "author": "herman" }] ]; array.sort((a, b) => a[1].author - b[1].author) console.log(array)You have the right idea, but you need to use a differet way of comparing. The subtraction operator on non-numeric strings always yields NaN, which is useless for comparison.
You could use localeCompare, which reutrns 1, 0, or -1:
array.sort((a, b) => a[1].author.localeCompare(b[1].author)) 
A working solution using .sort method of an array and using localeCompare method to sort based on the strings
var array = [ [ "ifke", { "title": "secure", "author": "admin" }], ["lottery", { "title": "The lo", "author": "anton" }], ["short-content", { "title": "Short Content", "author": "scott" }], ["ziddler", { "title": "The Fiddler", "author": "herman" }] ]; array.sort((a,b) => a[1].author.localeCompare(b[1].author)); console.log(array);
array.sort((a, b) => a[1].author.localeCompare(b[1].author))
