Sort JavaScript Array With Both Strings and Numbers into a numbers only array and a string only array

I have an array containing the following data:

var arr = [30, "Chad", 400, 700, "Brian", "Zander", "allen", 43, 50]

I want to sort this array into an array containing just the numbers (from lowest to highest) and another array containing just the strings (in alphabetical order--the "a" in Allen is currently lowercase but still should go before the other names).

I assume I would use a for loop combined with an if/else statement but am not sure of the syntax. Any help would be appreciated.

You can use the filter and sort function . By default array will be sorted comparing the items as strings. So with numbers you need to explicitly pass the sorting function.

.sort((a,b) => a - b);

For strings, the default comparing is good.

var arr = [30, "Chad", 400, 700, "Brian", "Zander", "allen", 43, 50]

var numbers = arr.filter(item => typeof item === 'number').sort((a,b) => a - b);
var strings = arr.filter(item => typeof item === 'string').sort((a,b) => a.localeCompare(b));

console.log(numbers);
console.log(strings);
