What Platform is Used to Run JavaScript Code Online?



JavaScript is the most used and preferred programming language.

Programmers use JavaScript to create dynamic and interactive web content. JavaScript is utilized in nearly 97% of websites worldwide as a web-based language. 

Since JavaScript is a high-level programming language, a JavaScript compiler must translate the source code into easily readable machine code to run the program successfully on a computer. 

You can be an expert in JavaScript or an aspiring learner just about to embark on a journey to run JavaScript; knowing the right platforms to run JavaScript code online is the first and foremost. 

Hence, we have curated this blog post carefully to outline different platforms where you can run JavaScript code online. 

Learn all the nits and grits of JavaScript and the platforms supporting JavaScript, and strengthen your knowledge!

JavaScript Overview

JavaScript, commonly known as JS, is an object-oriented, lightweight computer programming language. The language is curated by following the ECMA Script Standards. Programmers primarily use JavaScript as a necessary tool for designing the behavior of different web pages. 

It is a best-fit programming language for beginners for its easy coding language. Hence, creating superfast web applications and websites using JavaScript is easier.

For its versatile nature, JavaScript, by default, is built into almost every modern web browser. 

Hence, you do not have to look for different software or setup to run JavaScript code online. Google Chrome, Microsoft Edge, Safari, Mozilla, and other web browsers support JavaScript.

JavaScript Features

This popular programming language possesses the following features, making it one of the best for creating web applications:

  1. It is compatible with every modern web browser.
  2. It provides a good user experience.
  3. Type-less code is an added feature of JavaScript. 
  4. It is an interpreted and lightweight language. 

Let’s hop into applications of JavaScript for a better understanding. 

JavaScript Applications

JavaScript is used in an array of applications. Some of them are as follows:

  • Game development
  • Mobile application development
  • Back-end development for web applications
  • Interactive front-end development
  • Manipulation of BOM (Browser Object Model) and DOM (Document Object Model)

JavaScript Compiler

Earlier, you read that a JavaScript compiler is necessary for converting the source code into bytecode or machine code. 

However, it is slightly different from the traditional compiling method. JavaScript need not be compiled before as it is already designed in a way that it can directly run by the JavaScript engine. 

However, you can use a JavaScript compiler like Just-In-Time (JIT) or Ahead-of-Time (AOT) to enhance the execution process.

Syntax

You must learn about the variables and Loop to run JavaScript code successfully. Variables are denoted with let, var, or consent keywords that contain multiple data like objects, strings, Boolean, arrays, and numbers. 

Now that you have learned an overview of JavaScript let’s initiate the main discussion- platforms.

Advantages and Limitations of Using Recursion in Programming

Image
Recursion is a popular programming technique that allows functions to call themselves to solve a problem. It is widely used in many programming languages and has its advantages and limitations. In this essay, we will explore both the advantages and limitations of using recursion in programming. Recursion is a powerful programming technique that involves a function calling itself until a certain condition is met. There are several advantages of using recursion in programming: Simplifies complex problems: Recursion is often used to simplify complex problems by breaking them down into smaller, more manageable sub-problems. This makes it easier to understand and solve the problem at hand. Reduces code complexity: Recursive functions can be used to write elegant and concise code by reducing the need for repetitive code blocks. Recursive solutions can often be shorter and more concise than iterative types of sorting . Easy to read and understand: Recursive solutions can be very easy to re...

Python is a much-appreciated general-purpose programming language. It is utilized in various industries, including web development, machine learning, and desktop applications.  Luckily, the language Python has an easy-to-use syntax suitable for beginners. This makes Python an excellent language for novices to learn.  In this blog article, all of Python's fundamental concepts will be covered. You will feel confident using a  Python online compiler  to create projects. Let’s get started! About Python Python is one of the most used programming languages in modern-day, created by Guido van Rossum and released to the public in 1991. The public has free access to the source code for Python using a Python online compiler, and there are no restrictions on how it may be used or distributed, including for profit.  Practically anything may be produced with it for web development, including online web apps, mobile applications, tools, machine learning, data analytics, and m...
