#6 Get total sum of function arguments | how to add number of function arguments, interview question

In this video, we’ll explore how to create a JavaScript function that takes multiple arrays as arguments and calculates the total sum of all the numbers in those arrays. This is a great example of working with rest parameters, loops, and array methods like reduce() to solve real-world problems effectively. We’ll start by identifying common mistakes when writing the function and then move on to correcting those errors step by step. By the end, you’ll have a clean and optimized solution to sum all numbers across multiple arrays in JavaScript! 🔥 What you’ll learn: ✔ How to use the ...args (rest parameter) in JavaScript. ✔ How to handle multiple arrays and add their elements. ✔ The importance of initializing values correctly. ✔ Using reduce() like a pro.    / @mrfullstack
