Below is the JavaScript code for array sorting by level:Open Compiler const arr = [{ _id: 100, level: 3, parentId: null, }, { _id: 101, level: 2, parentId: 100, }, { _id: 102, level: 2, parentId: 100, }, { _id: 103, level: 2, parentId: 100, }, { _id: 104,...
Sorting Object Arrays JavaScript arrays often contain objects: Example constcars = [ {type:"Volvo", year:2016}, {type:"Saab", year:2001}, {type:"BMW", year:2010} ]; Even if objects have properties of different data types, thesort()method can be used to sort the array. ...
Sorting in Javascript withsortuseslexicalsorting by default, which means it will sort in alphabetical order. That's fine for strings of characters, but it means that arrays of numbers don't sort in numerical order! To fix that, we'll pass a custom comparator function tosort. The function ...
