JavaScript is undoubtedly one of the best languages to learn as a developer, whether you’ve been at it for years or are just starting out. More than 97% of today’s websites are powered by JavaScript. Regardless of what field you work in, you’ll likely be exposed to JavaScript at some point, as the language is firmly entrenched in the online world.
A good programming language is one that newcomers can learn fast. This is one of the reasons why JavaScript is so popular – it’s possible to learn Javascript quickly and with minimum fuss.
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.
Every coder is told to learn JavaScript, seeing that it’s the foundation of the world wide web. And… every coder is taught that C++ is one of the most useful modern coding languages to learn. So no matter if you’re brand new to the coding world, or you have a few languages under your belt, you might be wondering whether you should tackle JavaScript vs C++ for your first (or next) language.
When comparing programming languages, it’s not often that you come across two that actually work well together, but that happens to be the case when it comes to PHP and JavaScript.
So you’re a fan of web development? Great! You’re probably already familiar with JavaScript (if not, check out our JavaScript course here) and may have heard of Node.js as well. But which one is better, and how are they different? When should you pick Node.js vs JavaScript?
When broken down into core features – like programming style and code execution – JavaScript and Ruby seem deceivingly similar, but there are a few constitutional differences.
Really good JavaScript projects for beginners can be tough to find. Sometimes they’re too hard, or assume too much prior knowledge. Sometimes they’re actually too easy, and don’t push you to develop any solid JavaScript skills. (Cough cough, that tic-tac-toe game I know you’ve probably seen recommended about a thousand times by now.)
JavaScript (JS), once regarded as simply a “glue language”, has gone on to become the most popular programming language in the world.
HTML, CSS, and JavaScript are the most important tools in your arsenal for all your web design escapades. Rather than compete, they complement and augment each other, and their power expounds when they’re combined – like internet Power Rangers.
Whether you’re new or old to the computer science community, you’ve probably asked yourself, “What is TypeScript?” and if you haven’t, it won’t be long before you do.
Versatile, powerful and ever-present, JavaScript is the world’s most used programming language (for eight years and counting!) and shows no signs of slowing down. Check out these 20 practice interview questions for JavaScript! If you’re on the job-hunt for an entry-level position, read on.
“Why learn JavaScript?” I asked my sister when she was in college and starting to pick up the fundamentals of JavaScript. “Isn’t it ancient? Do people still use it?”
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.
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.
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.
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’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.
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.
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 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.
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.
Quick answer: use crypto.randomBytes() for cryptographically secure randomness in Node.js. const { randomBytes } = await import("node:crypto"); const buf = randomBytes(256); console.log(`${buf.length} bytes of random data: ${buf.toString("hex")}`); crypto.randomBytes() is a cryptographically secure random number generator based on openssl. Depending on the operating system of the user, randomBytes will use /dev/urandom (Unix) or CryptoGenRandom (Windows).
