Why TypeScript Jumped to #50 in July’s TIOBE Index

TIOBE’s July 2023 programming language index has been released, with TypeScript emerging as the month’s headline language.

The top‑20 rankings are shown in the chart below:

C remains firmly at the top, continuing its rapid growth, while Java holds steady, widening the gap between the two compared to the previous month.

Note that SQL was re‑added to the TIOBE index in February 2018; lacking historical data, its index appears to have surged suddenly.

Although not in the top‑20, TypeScript rightfully became the focus of the month. After entering the top‑100 for the first time in the previous month, it jumped to rank 50 this month, crossing the 50‑point threshold. TypeScript is a strict superset of JavaScript that adds extensive type safety, and its prospects are considered strong. Angular, which is gaining popularity, is built entirely around TypeScript, contributing to its rise. While the major JavaScript framework React has not yet adopted TypeScript, this is likely only a matter of time.

Other highlights this month include Objective‑C returning to the top ten (potentially temporary), Lua climbing from 36th to 25th, F# moving up 19 places to 36th, and Haskell re‑entering the top 50 at rank 44.
