Why TypeScript Matters
Introduction
TypeScript is an open-source programming language developed and maintained by Microsoft, Google and other contributors. It is a superset of JavaScript that compiles to plain JavaScript, and can be used to develop large applications with strong typing but without any need for complex compilation steps. Written in TypeScript, Angular 2 is roughly twice as fast as its predecessor and offers improved support for mobile devices.
TypeScript’s popularity has grown quickly since its release in 2012, thanks largely to the backing of some major players like Google (which uses it for Angular) or Microsoft (which has adopted it on several fronts). And while many developers are still more comfortable with JavaScript than TypeScript because they already know how to use it well enough, this might not always
What is TypeScript
TypeScript is a fantastic language that bridges the gap between JavaScript and Angular. This means that TypeScript can be used to get the best of both worlds when they are used together in order to create large applications with strong typing but without any need for complex compilation steps.
This programming language was created by Microsoft, Google, and other contributors. When using TypeScript in your Angular 2 app, you will see it running smoothly on your desktop without any lag or sputtering when you load up the program.
If you do not want to use Angular 2 or TypeScript in general, then this article may not be for you.
Why should I use TypeScript
TypeScript is an open source, developed by Microsoft and Google. It is a subset of JavaScript that compiles to plain JavaScript, and can be used to develop large applications with strong typing but without any need for complex compilation steps. Written in TypeScript, Angular 2 is roughly twice as fast as its predecessor and offers improved support for mobile devices.
What's new in TypeScript
TypeScript offers these benefits:
Type annotations make it easier to read and pinpoint specific issues on larger pieces of code.
Optional static type checking allows for faster compilation.
Class definitions make refactoring simpler and more reliable, while still supporting runtime dynamism.
How to use TypeScript
TypeScript is different from JavaScript in that it allows you to use these variable types.
TypeScript can handle more than just numbers, for example, it also handles booleans, strings and any other data type that JavaScript does. It can handle some unique data types that are specific to TypeScript, like the "number" type used to store complex numbers.
TypeScript can also help you write your code better so it's easier to maintain. For example, let's say you named a function 'foo'. You can use TypeScript to specify which arguments this function should take. If the function takes an argument called 'bar', you would write var foo = (bar: string) => { } (or (arg: string) => { }) depending on whether you prefer your code to be more verbose or concise. TypeScript will then check the function and ensure that bar is indeed a string.
TypeScript also has its own Object Oriented programming model which it calls "classes". Classes in TypeScript closely resemble classes in Java and C++: methods
When to use TypeScript
TypeScript can be used to develop large applications with strong typing, but without the need for complex compilation steps. It is an open-source programming language developed and maintained by Microsoft, Google and other contributors. TypeScript is a superset of JavaScript that compiles to plain JavaScript, and can be used to develop large applications with strong typing but without any need for complex compilation steps.
One of the main reasons why you would want to use TypeScript is if you are developing big project with multiple files. It is easier for programmers who are working on the project to find what they are looking for in the code when they use TypeScript because it has advanced type checking.
With Advanced type checking, programmers can benefit from more safety which means it is easier to find obvious errors in your code, and refactoring tools work better with TypeScript. Type checking also enforces stricter validation on parameters and return types of functions.
HTML5 -based mobile web apps often run into the wall when trying to go beyond simple use cases like dashboard apps for stock trading, weather reporting or social media feeds. This is because HTML5 is not really well suited for more complex scenarios. Angular 2, however, provides an easier way of building rich web apps so you no longer have to rely solely on traditional JavaScript or jQuery based solutions. TypeScript plays a crucial role in making this possible by adding strong typing to the code so programmers can enjoy the benefits of safety, refactoring tools and more.
The benefits of using Typescript over JavaScript
TypeScript is an open-source programming language developed and maintained by Microsoft, Google and other contributors. It is a superset of JavaScript that compiles to plain JavaScript, and can be used to develop large applications with strong typing but without any need for complex compilation steps.
Written in TypeScript, Angular 2 is roughly twice as fast as its predecessor and offers improved support for mobile devices. A large number of developers use the tooling, IDEs, editors, etc. that are offered by the company that created the product in order to make their job easier. The benefits of using Typescript over JavaScript are obvious when one considers the benefits offered by the company that created it. Typescript offers code completion tools that are used by all other modern languages. Completion suggestions for variables, classes and functions can be seen as you type without having to complete lines of code manually. This saves a lot of time during the development process.
The editor support offered by Microsoft is excellent, easily surpassing anything that can be found elsewhere. Visual Studio Code, Microsoft's offering to the open source community, is a free cross-platform development tool based on web technologies. TypeScript can be better understood within the context of JavaScript itself. The latter was originally designed for writing small programs that do not require any strong typing capabilities. Over time, though, people began using it for building larger applications. This is when the need for tools like Typescript arose, which brought JavaScript to a whole new level in terms of reliability and supportability. Due to its strong type system, TypeScript can catch many errors at compile time rather than run-time.
Disadvantages of using Typescript over JavaScript
A disadvantage of using TypeScript is that it requires a transpiler to convert the TypeScript code into plain JavaScript. This might cause problems for people who are not familiar with TypeScript. Another disadvantage is that it doesn't have as big an ecosystem as JavaScript.
Conclusion
TypeScript is an open-source programming language developed and maintained by Microsoft, Google and other contributors. It is a superset of JavaScript that compiles to plain JavaScript, and can be used to develop large applications with strong typing but without any need for complex compilation steps. Written in TypeScript, Angular 2 is roughly twice as fast as its predecessor and offers improved support for mobile devices. In this article we have seen some of the benefits of using TypeScript over just pure JavaScript such as static type checking which eliminates bugs at compile time rather than runtime, better performance due to faster execution times from compiled code instead of interpreting it on each run through your application's source code or browser DOM tree - all while retaining the ability to write expressive JSX/ES2015/2016 code and taking advantage of its rich community and ecosystem.
