React and other libraries, and JavaScript Framework
Posted: Wed Feb 19, 2025 6:51 am
A JavaScript library is a set of reusable code that you can put into your project. It saves you the work of developing a feature from scratch when other developers have already done it.
There are over 83 libraries, each of which has a specific purpose. For example, Chart.js is a library that allows you to easily create charts and graphs for your website.
One JavaScript library you should be familiar with is React. React is a free and open-source library maintained by Facebook. It is used to build user interfaces for single-page applications and is currently the most popular JavaScript library.
JavaScript frameworks are similar to libraries. They both provide reusable code, but the usage is a little different.
When you use a library, you are in charge of the flow of your application. You decide where in your code to call a component from the library.
With frameworks, you're connecting your code to the framework. Instead of your code calling the library, the framework calls your code at designated points.
A couple of popular frameworks that you should be familiar with are Angular.js and Vue.js.
Node.js
Node.js is often mistakenly called a framework or programming language, but it is a runtime environment for frontend and backend development.
Typically, JavaScript is executed by the user's browser. Node.js allows you to run your JavaScript code outside of the browser.
Node.js is popular because it makes web development argentina phone number data more efficient. It allows developers to create the frontend and backend of an application using a single programming language.
You may have to use Node.js in your frontend development work, so it's good to learn it. You can download and install it yourself so you can practice.
Ajax
Ajax is short for Asynchronous JavaScript and XML. Ajax is not a technology in itself , but rather a set of programming techniques.
Ajax is all about asynchronous development. That means you can update the content of part of a web page without reloading the entire page.
A typical example is autocomplete. When you start typing a query into Google, the search engine offers you autocomplete options. You can do this without reloading the entire search results page.
Many frontend developer jobs require familiarity with Ajax concepts. Once you've mastered JavaScript, online tutorials can teach you how to use it for Ajax.
Other programming languages
Depending on the project you're working on, you may want to learn other programming languages besides JavaScript.
