TypeScript: What is it?
JS is TypeScript. That means any valid .js file may be renamed to .ts then compiled with additional TypeScript files.
ECMAScript and TypeScript
If you are developing using Typescript you need to learn what the ECMAScript specification is. It is a standardized specification of a scripting language. There are 6 ECMA-262 editions available. Version 6 of this standard has the codename “Harmony”. It is affiliated with the ECMAScript6 specification.
Why to use TypeScript?
What are the Benefits of TypeScript?
It supports Object-Oriented Programming ideas such as inheritance, interfaces, classes, and so on.
Compilation− JS is an interpreted language. So, it must be run to test that it’s valid. That means you will write all of the codes only to discover no output, in case there’s an error. Therefore, you must spend hours attempting to locate bugs in the code.
TypeScript’s transpiler offers an error-checking feature. It’ll compile the code then produce compilation errors if it locates some syntax errors. It helps to emphasize the mistakes before the script gets run.[adsense]
TypeScript, at its heart, has these three components –
TypeScript Language Service − This “Language Service” exposes an extra layer surrounding the core compiler pipeline, including editor-like applications. This language service supports the standard set of typical editor operations such as signature help, statement completions, colorization, code outlining and formatting, and so on.
Language – It will comprise of the type annotations, keywords, as well as syntax.
