To raised assess the expansion prospects of programming languages, JetBrains’ 2024 report introduces the JetBrains Language Promise Index, which relies on the expansion in utilization of the language over the previous 5 years, the soundness of this development, the share of builders meaning to undertake the language, and the share of the language’s present customers who need to undertake one other language.
Primarily based on this components, the “undisputed leaders” of the JetBrains Language Promise Index are TypeScript, Rust, and Python, JetBrains reported. TypeScript utilization has surged from 12% in 2017 to 35% in 2024, whereas Python utilization has grown from 32% in 2017 to 57% in 2024 and Rust utilization has grown from 2% in 2018 to 11% in 2024. Java utilization, in the meantime, has slipped from 47% in 2017 to 46% in 2024, though it had surged to 54% in 2020.
Regardless of its beneficial properties, TypeScript won’t substitute JavaScript, in keeping with the report. JavaScript stays probably the most widespread and basic applied sciences within the software program growth trade. Nonetheless, TypeScript gives advantages over JavaScript together with early error detection throughout growth, improved code high quality, compile-time error catching, extra dependable refactoring, and native help for ECMAScript 2015 (ES^) modules.
