- As code increases in volume, it becomes messier and difficult to organize.
- Lack of debugging feature.
- Absence of browser support making it difficult to run on older browsers.
- Poor client-side Security.
With of these downsides to JS, the natural fix would be a more robust solution.
For example, as a team lead with a project that involves simulating object orientation, the better choice of a language for such a job would be TypeScript.
What is TypeScript offering?
No Learning Curve Required

Get in! TypeScript couldn’t have come at a better time.
