Microsoft introduced the beta version of TypeScript 7.0, the largest update in the history of the language. Thanks to the transition to a new “engine” written in the Go language, developers will be able to check errors and build projects 10 times faster, xrust reported. The new version has already been “baptized by fire” in Google, Slack and Miro and is ready for everyday use.
Revolution under the hood
The main change in TypeScript 7.0 is a complete replacement of the internal architecture. Previously, language tools ran on jаvascript, which created speed limitations on large projects. Now Microsoft has rewritten the compiler (the program that turns code into a running application) in the powerful Go system language. For programmers, this means one thing: what used to take a minute to check will now only take a few seconds.
Tested by market leaders
The new version is not just an experiment. Teams from global IT giants worked on it for a year. Among those who have already implemented TypeScript 7.0 in their processes are Bloomberg, Canva, Figma, Google, Notion and Slack. The experience of these companies confirms that the transition to a new base makes the development process incredibly smooth and fast.
How to upgrade to the new version?
Microsoft made sure that the transition was as painless as possible. TypeScript 7.0 can be installed next to the old version 6.0 to compare speed. If your code worked without errors in the sixth version, it will run in the seventh, but much faster.
General code cleaning
Along with acceleration, TypeScript 7.0 also brings purity. The developers have finally abandoned support for some outdated and unsafe functions. For example, default settings are now more restrictive, which helps catch errors early and make sites and applications more reliable for end users.
