Pros and Cons of JavaScript and Dart that you need to know

For developing cross-platform mobile apps, both JavaScript and Dart are great choices. But they are not the same when looked at from the developers’ point of view.

JavaScript has emerged as the language for rendering web pages along with HTML and CSS technologies. This language has later extended its arm to server-side, non-browser, and mobile application development. Dart is a programming language initially used internally at Google to build web, server, and mobile applications. JavaScript supports both OOPs and functional programming style, whereas Dart compiles the source code similarly to other programming languages. Now you might be thinking that what might be the difference between the pros and cons of using JavaScript and Dart. The answer to your question can be best given by experts from the Best Software Training Institute in Durgapur.

Let's take a look at the pros and cons of JavaScript and Dart in short. If you go and ask a developer which language is prominent- JavaScript or Dart, they will answer you according to their choice. Every developer uses a programming language depending on the needs of the project and the strength of their developer and their team.

Pros of JavaScript

  • JavaScript can run on every device; that's why it can be used for both frontend and backend.
  • The programming language has a huge community and great frameworks available online.

  • It is approximately two times faster than JavaScript.

  • This language is used extensively for the Flutter mobile UI framework.

Cons of JavaScript

  • The programming language JavaScript has some libraries which are not of good quality.
  • As it is a dynamic language, so the programmers can make big mistakes easily.
  • As new frameworks land after a regular interval, so there are constant changes.
  • Client-side security in the language leaves a lot to be desired.
  • If one error occurs, then it can crash an entire website.
  • Multi-threading support is not available in JavaScript.
