The article discusses the transition from a legacy JavaScript project to TypeScript, motivated by increasing code complexity and declining relevance. The development team recognized TypeScript's advantages, including improved code understandability, static typing, and alignment with modern tech. To gain management's approval, they highlighted potential cost savings through reduced bugs, decreased onboarding time, and increased productivity. Ultimately, these arguments led to the successful adoption of TypeScript, revitalizing both the codebase and developer enthusiasm.
One day, you wake up and decide you can't live without TypeScript in your legacy JavaScript project anymore. That's what happened to me and my colleagues, too.
The longer you develop an app, the more complex it becomes. With time, we realized that we couldn't ignore the following issues anymore.
TypeScript could help us: Handle increasing codebase complexity by implementing strict rules and following them. Make the codebase more understandable.
These benefits were enough to convince the development team to adopt TS, but we still had to convince the management team of the reason.
