Unordered string array comparison with lodash

Question

I'm trying to compare two unordered arrays of strings with lodash. I have tried using the isMatch function but it doesn't seem do what I want. Here's what I have tried:

var arr1 = ['foo', 'bar']
var arr2 = ['bar', 'foo']
_.isEqual(arr1,arr2) //should return true, but instead it returns false

Thanks.

`_.chain([arr1, arr2]).map(sortBy).reduce(_.isEqual).value()` — marzelin, Sep 03 '18 at 13:39

You need to sort() the arrays to maintain the sequence for comparing it with _.isEqual()

var arr1 = ['foo', 'bar']
var arr2 = ['bar', 'foo']
console.log(_.isEqual(arr1.sort(),arr2.sort()));
