The IT Pro Podcast: Why everyone should be using TypeScript
While converting 50 million lines of code to a new language was no easy task, Bloomberg is now reaping the rewards

Migrating to a new technology is always challenging, but it's even more daunting when your estate includes 2,000 engineers, 10,000 applications and 50 million lines of code. That was the challenge faced by FinTech powerhouse Bloomberg when it made the transition from JavaScript to TypeScript, but with the migration process now well underway, the organisation is reaping big benefits in the hygiene and maintainability of its codebase.
This week, we're joined by Thomas Chetwin, the co-chair of Bloomberg's JavaScript guild, to learn more about why the company made the switch, the challenges it faced during the process and why everyone should be using TypeScript.
