Why should You Use TypeScript Over JavaScript?

When It comes to client-side development, CSS, HTML, and TypeScript come first in mind. However, there is a huge debate happening about TypeScript vs JavaScript. However, it is important to choose the best programming languages that also match the unique needs of your software development project. 

For a decade, TypeScript has been gaining popularity, even though it was listed at the top of promising programming languages. It is commonly used by Angular, which is the widely used frontend framework. It is a superset of Java and supports optional typing. In other words, TypeScript is another version of JavaScript with static typing features. Nowadays, more than 65% of software developers are using TypeScript as it helps in identifying most of the JavaScript errors.

Why Should You Use TypeScript  Over JavaScript?

More Dependability:

TypeScript is more dependable as compared to JavaScript, it allows developers to avoid code rewrites and mistakes. Along with this, it invalidates many errors that affect JavaScript codebases and helps in getting internal feedback to make improvements in writing new codes and refactoring.


TypeScript is considered more explicit as compared to JavaScript. It plays a crucial role in developing large-scale and complex software development projects. It is useful in clearly directing focus on software development while having interaction between many components.

Early Detection of Bugs:

When talking about the difference between JavaScript and TypeScript, TypeScript detects 15% of the errors during the compilation phase. This makes it easier for developers to save time and focus on resolving logic errors instead of prioritizing the common errors. In addition to this, code submission to the compiler can help in minimizing the number of testing and quality assurance processes.


With static typing and self-expressive aspects, it is easy to determine the design intent of the developer when the code was initially written. TypeScript is extremely helpful in a project in which remote collaboration is involved.

OOP Principles:

TypeScript supports class-based OOP principles. Here, OOPs are object-oriented programming principles that include classes, inheritance, and interfaces. The OOP principle helps in developing scalable, well-organized code that becomes more important when your project demands customization due to increasing complexity and size.


TypeScript offers greater compatibility across different browsers and platforms as it offers a TypeScript Compiler (TSC). That means the device or platform that supports JavaScript also supports TypeScript as the compiler makes the conversion to vanilla JS. Also, TypeScript involves IDEs (integrated development environments) that enable the transition of codebase subsets and even the new software application.

The Popularity of TypeScript in the Industry

In StackOverflow’s 2020 Developer Survey, the results showed that TypeScript is the second most popular programming language used by software developers. TypeScript is widely used in renowned software products such as Asana, Slack, and Visual Studio Code.  Even many JavaScript tools are written using TypeScript such as libraries  ( yWorks, ZoomCharts, or GoJS) and frameworks (Aurelia, Angular, or Ionic). Most importantly, many industry leaders such as  JetBrains, Ericsson, Microsoft (duh!) and Ubisoft are using TypeScript. That means it is clear that TypeScript is the popular choice among many enterprise-level businesses.

The Final Remarks

TypeScript can be a trusted tool used by software developers who are familiar with JavaScript. It not only makes complex projects easy by offering enhanced code writing toolkits. It offers top benefits to both developers and the project owner. Due to little and good quality coding, this programming language helps teams to gain improved performance with faster time to market, fewer errors, and so on. There is no doubt that TypeScript has the potential to revolutionize software development and bring more opportunities to business.
