Imagine you have an array of values; numbers or strings for example. You might have the need to remove one or more elements. For example you might want to know:
How to remove specific item from array in JavaScript
How to remove last item from array in JavaScript
How to remove duplicate item from array in JavaScript

In this tutorial we’ll explore the above scenarios and find solutions for solving different ways of removing items from an array.

We’ll start off simple by looking at how to remove items from an array using JavaScript’s pop function. This is a function that’s available on all arrays and it will remove the last item from an array and you can optionally store it too.

Another option is to use the shift function in JavaScript. This will actually take the item from the front of the array and in a similiar way to pop, you can store the value removed.

With those two basic options covered, let’s look at some of JavaScript’s filter higher order function to remove any items that don’t meet a certain condition. This can be a great way of removing lots of items from an array when you want rid of values based on a certain condition.

Finally, we can use the filter function mentioned above when we want to remove duplicate items from arrays in JavaScript. We’ll cover this as a final example as this is quite a common thing required for a Junior Developer to do.

About the Site 🌐

This site provides links to random videos hosted at YouTube, with the emphasis on random. 🎥

Origins of the Idea 🌱

The original idea for this site stemmed from the need to benchmark the popularity of a video against the general population of YouTube videos. 🧠

Challenges Faced 🤔

Obtaining a large sample of videos was crucial for accurate ranking, but YouTube lacks a direct method to gather random video IDs.

Even searching for random strings on YouTube doesn't yield truly random results, complicating the process further. 🔍

Creating Truly Random Links 🛠️

The YouTube API offers additional functions enabling the discovery of more random videos. Through inventive techniques and a touch of space-time manipulation, we've achieved a process yielding nearly 100% random links to YouTube videos.
