What Can We Expect in TypeScript 4.0

In my previous article, I talked about the new features in TypeScript version 3.9. Today, I will be peeking into TypeScript 4.0, which is expected to be released by August 2020. According to the iteration plan, it seems that they are working on various aspects, including language features, performance, infrastructure, and — most importantly — bugs.

In this article, I will go through a few features that are planned to be released with version 4.0

Microsoft Releases TypeScript 4.0 With Speed Boosting Features

icrosoft recently announced the availability of TypeScript version 4.0. The developers at the tech giant claimed that this version of the language represents the next generation of TypeScript with more expressivity, productivity as well as scalability.

Developed by the tech giant, TypeScript is an open-source programming language that is built on top of JavaScript by adding syntax for static type definitions. The types in this language provide a way to describe the shape of an object, providing better documentation as well as allowing TypeScript to validate that the code is working correctly.

According to the latest Stack Overflow Developers survey 2020, it secured the second position as the most loved language and  9th position among 25 programming languages as the most commonly used programming language by the developers. In one of our articles, we discussed how TypeScript weighs over other programming languages.

It is one of the fastest-growing programming languages among the developers. The motive behind this language is that while writing down the types of values and where they are used, developers can use TypeScript to type-check the code and let them know about mistakes before they run the code. TypeScript compiler can be used to strip away types from the code, leaving them with clean, readable JavaScript that runs anywhere.

In the present scenario, TypeScript is a core part of many developer’s JavaScript stack. The language adds optional types to JavaScript that support tools for large-scale JavaScript applications for any browser, for any host and on any operating systems.

The program manager of TypeScript, Daniel Rosenwasser, said in a blog post, “In our past two major versions, we looked back at some highlights that shined over the years. For TypeScript 4.0, we’re going to keep up that tradition.”

What’s New?

Based on the feedback by the developer’s community, TypeScript 4.0 includes many intuitive features that are focussed on boosting the performance of this language. Some of them are mentioned below-

Speed Improvements in build mode with –noEmitOnError

According to Rosenwasser, previously, compiling a program after a previous compile with errors under incremental would result in extremely slow performance when using the –noEmitOnError flag. The reason is, none of the information from the last compilation would be cached in a .tsbuildinfo file based on the –noEmitOnError flag.

But now TypeScript 4.0 changes this. The new update provides a great speed boost in these scenarios, and in turn, improves the build mode scenarios, which imply both –incremental and –noEmitOnError.

What’s New In Typescript 4.0?

Today I am going to talk about new features in Typescript 4.0.

TypeScript 4.0 comes with lots of new features to make JavaScript development easier.

Labeled Tuple Elements

You can label tuple elements.

You can write:

type Range = [start: number, end: number];

to restrict args to have a string and a number.

you can also write:

type Foo = [first: number, second?: string, ...rest: any[]];

to have rest entries in your tuple.

If your tuple has type Foo, then the tuple starts with a number and a string.

Then the rest of the entries can be anything.

Labels don’t require you to name your variables differently when destructuring.

For example, if you have:

function foo(x: [first: string, second: number]) {
  const [a, b] = x;
}

then you can name the destructured variables anything you want.
