Top 4 Practical Uses of JavaScript
by Zulie Rane - Data analysis and computer science techincal author
JavaScript is one of the most versatile programming languages, maybe even more flexible than Python. JavaScript is used on both the front and back end of web systems. Because of that, of the 1.8 billion websites in the world, 95% of them use JavaScript. It's hard to interact with the modern Internet, with its pretty graphics and interactive maps, without using JavaScript. Enable Marketing says the top four qualities of a visually appealing website are design and color, graphics and visuals, usability, and consistency. JavaScript is a major player in all four of those attributes.
JavaScript vs C++: 3 Factors To Choose Which Is Best For You

Converting an Array to a JSON Object in JavaScript
by Lane Wagner - Boot.dev co-founder and backend engineer
JSON, or "JavaScript Object Notation", is a highly popular data exchange format that's widely used in web development. In this post, we'll explore several simple methods for converting a JavaScript array into JSON data. Plus, we'll discuss the benefits of using JSON and how it can help improve your web development projects.
JavaScript vs Java - Differences, Similarities, and History
by Lane Wagner - Boot.dev co-founder and backend engineer
The naming of Java and JavaScript confuses many new programmers. They sound so similar, so one might think they have the same use-cases, similar properties, or maybe the same company created both languages. None of those assumptions are true! JavaScript is primarily used as a front-end in-the-browser language, like how we use it for boot.dev's courses. Java has been used for everything from games, to desktop apps, to backend APIs. Let's go over the differences between JavaScript vs Java in this quick read.
HLS Video Streaming with Node.JS - A Tutorial
by Lane Wagner - Boot.dev co-founder and backend engineer
In this quick tutorial, we'll build a robust video (or music) streaming API using Node JS. Don't worry, it's surprisingly easy since we will be utilizing a modern protocol, HTTP Live Streaming, or HLS.
How To Cache Images - React Native Expo (Managed)
by Lane Wagner - Boot.dev co-founder and backend engineer
Caching images in React Native can be easy, even if you are using Expo's managed workflow. The problem many devs run into is that React Native only supports caching images on IOS out of the box.
JavaScript With Statement Explained – A Deep Dive
by Lane Wagner - Boot.dev co-founder and backend engineer
JavaScript's built-in with statement specifies the default object for the given property and gives us a shorthand for writing long object references. More precisely, it adds the given object to the head of the scope chain.
JavaScript Map Function Explained - A Deep Dive
by Lane Wagner - Boot.dev co-founder and backend engineer
The built-in JavaScript map function returns a new array, where each element in the new array is the result of the corresponding element in the old array after being passed through a callback function. Later in the article, we'll do a deep dive into some more advanced concepts regarding the map function and its uses.
Which Method of Iteration in JavaScript is Fastest?
by Lane Wagner - Boot.dev co-founder and backend engineer
There are many ways to traverse an array in Javascript. In this benchmark, we will look at five different ways and the pros and cons of each. Keep in mind that these benchmarks were run in a Chrome browser on Codepen.io. Results will vary by browser/interpreter.
Singletons in ES6 - The Good, The Bad, The Ugly
by Lane Wagner - Boot.dev co-founder and backend engineer
Singletons are fairly controversial as far as I can tell, especially in JavaScript programming. Let's take a look at what they are, when to (maybe) use them, and when not to.
How to Recursively Traverse JSON Objects
by Lane Wagner - Boot.dev co-founder and backend engineer
I've found that it's pretty rare that I need recursion in application code, but every once in a while I need to write a function that operates on a tree of unknown depth, such as a JSON object, and that's often best solved recursively. Even though recursion is rare, it is important to recognize when a problem is best solved recursively so that we can implement a good solution when the time comes.
Secure Random Numbers in Node.js
