How do you add an array to another array in Ruby and not end up with a multi-dimensional result?

How to Combine Arrays in Ruby Without a Multi-Dimensional Result 😎🔗

Adding an array to another array in Ruby should be a straightforward process, right? But what if you're getting unexpected results and ending up with a multi-dimensional array? 🤔 Don't worry! In this guide, we'll address this common issue head-on and provide you with easy solutions to achieve the desired result. 💪

The Issue at Hand 🐛🔍

Let's start by identifying the problem in the context provided. The initial attempt looked like this:

somearray = ["some", "thing"]
anotherarray = ["another", "thing"]
somearray.push(anotherarray.flatten!)

The expected outcome was ["some", "thing", "another", "thing"], but instead, an unexpected nil element appeared in the resulting array. The question is, why did this happen? 🤔

Understanding the Problem 🤔📚

The issue lies in the use of the flatten! method. When you call the flatten! method on an array, it destructively flattens the array (i.e., removes all nested arrays and merges their elements into the original array in a single level). However, if there are no nested arrays present, the method returns nil. This behavior is what caused the unexpected nil element in the final array. 😣

Easy Solutions to the Rescue! ✨🚀

Now that we understand the problem, let's explore some quick and easy solutions to add one array to another in Ruby without ending up with a multi-dimensional result.

Solution 1: Using the Concatenation Operator (+) 🔄

The concatenation operator (+) allows us to combine two arrays into a new array without modifying the original arrays. Here's an example:

somearray = ["some", "thing"]
anotherarray = ["another", "thing"]
result = somearray + anotherarray

By applying the concatenation operator, result will be ["some", "thing", "another", "thing"], just as expected. 🎉

Solution 2: Using the Concatenate Method (concat) 📚

Another way to achieve the desired outcome is by using the concat method, which modifies the original array in place by adding the elements of another array to it. Here's an example:

somearray = ["some", "thing"]
anotherarray = ["another", "thing"]
somearray.concat(anotherarray)

After executing this code, somearray will contain ["some", "thing", "another", "thing"], which is exactly what we wanted. 🙌

Time to Act! 🛠️💡

Now that you have learned two easy solutions to add one array to another without ending up with a multi-dimensional result, it's time to put your knowledge into action! 💪 Choose the method that suits your needs and try it out in your own code.
