how to to Sort an Array of Mixed Data Types in JavaScript - TypeError Issues
I'm having a hard time understanding I'm working on a personal project and I've been banging my head against this for hours. I'm trying to sort an array containing mixed data types in JavaScript (strings and numbers), but I'm running into a `TypeError` when attempting to compare them. My goal is to have a sorted array where all numbers come first followed by strings, and within those categories, the values should be sorted in ascending order. Here's what I have so far: ```javascript const mixedArray = [5, 'banana', 3, 'apple', 10, 'orange', 1]; const sortMixedArray = (arr) => { return arr.sort((a, b) => { if (typeof a === 'number' && typeof b === 'number') { return a - b; } else if (typeof a === 'string' && typeof b === 'string') { return a.localeCompare(b); } else { // scenario arises here return typeof a === 'number' ? -1 : 1; } }); }; console.log(sortMixedArray(mixedArray)); ``` When I run this code, I get this behavior: `TypeError: want to read properties of undefined (reading 'localeCompare')` on the comparison function. I’ve tried ensuring that both variables are defined, but the behavior continues. I suspect the scenario might be related to how I’m handling the mixed types in the comparison function, especially in the else branch. I would appreciate any insights or best practices for handling this kind of sorting in JavaScript. Is there a better approach to deal with mixed data types that would avoid this behavior? This is part of a larger API I'm building. How would you solve this? I'm working in a CentOS environment. I appreciate any insights!
