Today, JavaScript and TypeScript are among the most popular languages in the development world.
These two programming languages are mainly used for the development of web applications, but recently, TypeScript has experienced rapid growth since RxJS and Angular started to adopt it.
Elitech Systems offers you today a comparison of these two languages so that you can make your opinion on it
Presentation
As we have already seen, JavaScript is a scripting language for creating interactive web pages. It is a client-side programming language that requires no resources from the web server.
The main idea behind the development of this language was to make a complementary scripting language, just like Microsoft has Visual Basic to C ++.
Today, you can use JavaScript with many different technologies such as XML, REST APIs, and many more. However, JavaScript was not designed to build complex applications. Now let’s talk about TypeScript, which is a modern JavaScript language compiled to write simpler and clearer code. In other words, adopting TypeScript in a JavaScript development project can help you build a more robust application.
In short, TypeScript is designed to develop large-scale applications that can be transcompiled into JavaScript.
Why choose JavaScript?
SMALL PROJECT
TypeScript can be excessive for small projects or development teams. Therefore, JavaScript can be the ideal choice for developing small projects.
BUILD TOOLS
TypeScript requires the addition of a mandatory build step to execute JavaScript. But today, it is also rare that developers do not use compilation tools for the development of JavaScript applications.
SOLID TEST PHASE
If you already have a solid JavaScript team that you can rely on and can implement test-driven development, then using TypeScript is not worth the cost.
DEPENDENCIES
If your project involves the use of libraries and depending on these dependencies, these packages may no longer be maintained or may become incorrect in the future.
In other words, if you have to import type dependencies into your application development, you will lose the advantage of TypeScript.
Therefore, it is best to use JavaScript for projects that require dependencies.
Why choose TypeScript?
BIG PROJECT
If you are creating an enterprise level application or product in which the system structure is required, then TypeScript is recommended. The reason is that TypeScript makes it easy to develop and maintain the project with fewer bugs.
On the other hand, if you choose to develop a large application using JavaScript, the following errors are inevitable:
- No new JavaScript API is available on cross-platforms and browsers.
- There will be a lack of object oriented programming
- No basic project structure
CASTING TYPE / HINTING TYPE
Unlike JavaScript, TypeScript uses Type Casting and Type Hinting to give a number to a variable.
Once a number is assigned, TypeScript then displays the error when writing the encoding so that developers can resolve it before deploying the final code.
MULTI-NAVIGATORS
If you are creating an application that attempts to use all the functionality of JavaScript and targets multiple browsers, you don’t need to use different authoring tools like Webpack or Gulp.
TypeScript allows you to write code only once and specify at which point which browser to target.
Conclusion
Choosing one language over another depends solely on the purpose and functionality of the applications. However, using Typescript has more advantages. Its popularity and use are increasing considerably. The project improves with each new version and more interesting features are added with the new versions.
