Technically, TypeScript is a variation of JavaScript, the number one language for a long time. It first turned out in 1995, JS brought interactivity to previously lifeless sites and changed the front-end improvement scene. Presently, 95% of sites take advantage of JavaScript on the client-side, with many running JS toward the back. It is likewise utilized for mobile application development by a full stack development agency. However, JS doesn’t come without disadvantages. The significant concern is that this language wasn’t at first implied for building enterprise-level applications. Also, that is the place where TypeScript steps in. Kinfolk to JS in terms of syntax and semantics brings several additional tools that grow productivity and encourage the making of huge codebases.

Thus, Google picked TS to assemble Angular, targeted at large-scale applications and the essential language for creating Angular applications. However, Microsoft’s solution is also viable with all JS libraries and structures and can be utilized to make software with React, Vue, or other technology within the JS ecosystem. This versatility alongside special tooling makes TS perhaps the most cherished language, as per the 2019 Developer Survey by Stack Overflow.

Because browsers aren’t ready to peruse TypeScript code right now, it should be changed over to plain JavaScript before it’s delivered. Then, after automated transpiling — the procedure of translating one high-level language into another dialect — the code can be executed in any platform or server equipped with JavaScript motors. The latter, in turn, assembles JS into machine-level code.

TypeScript Pros: what makes TypeScript a solid match for large projects

TypeScript acquires significant pros of JavaScript, yet in addition, it offers extra advantages coming from static typing and different concepts specific to TS. They demonstrate particularly valuable for the large-sized codebase and distributed teams working on a similar task.

Early spotted bugs 

Scientists found that TypeScript identifies 15% of regular bugs at the assembly stage. Although a long way from 100% results, this sum is vast enough to save engineers time and focus on correcting mistakes in the logic— instead of catching regular bugs. Pushing the code through a compiler additionally decreases the volume of quality assurance and testing activities.


With TypeScript, everything stays how it was at first defined. So, for example, if the variable is announced as a string, it will consistently be a string and not transform into a Boolean. This upgrades the likelihood of functions working the way at first intended. 


Due to adding strict types and different components that make the code more self-expressive, you can see developers’ plan intent who initially wrote the code. It’s particularly significant for distributed teams working at a similar undertaking. A code that justifies itself can offset the absence of direct communication between colleagues.

TypeScript cons: what issues it makes 

There isn’t anything unique in this world, and TypeScript is no particular case. Generally, its weakness started from its qualities.

False static typing

Engineers mastering C#, C++ or Java regularly contend that TypeScript is undoubtedly not a simple statically typed language. Aside from the way this element is optional for TS, it is transpiled into untyped JavaScript in the long run, so there is always the danger of unusual type conversations at runtime. 

One more JavaScript to learn 

We conceded that it would be relatively simple for JS designers to learn TS in the past segment. However, regardless of this similarity, they still need to put time and effort into learning types and some TS-explicit constructs. In this way, if your organization intends to move to TypeScript and has JS devs with no past involvement in TS, they will not hit 100% productivity immediately. 

Bloated code 

Upgraded code readability brought by recently mentioned syntactic sugar and type annotations has its disadvantages. To begin with, you need to compose more code, which has the capability of slowing down the development process. Second, additional annotations make TS documents larger than those written in plain JS. The distinction in the number of code lines relies upon various factors. Interestingly, all the additional features will vanish after being transpiled. Eventually, the browser will execute plain JavaScript.


TypeScript mobile app development keeps on developing, with its 3.8 adaptation not far off. At the hour of composing, the delivery competitor was accessible, and the creation delivery will accompany a similar arrangement of overhauls and some basic bug fixes. Anyway, what significant enhancements does the new form bring? 

The changes are new syntax for type-just imports and exports, backing for ECMAScript private fields and other additions or alterations will serve a similar worldwide idea — to bring productivity, reliability, and predictability to the somewhat tumultuous JavaScript world.
