Migrating from JavaScript to TypeScript

The "Migrating from JavaScript to TypeScript" workshop is designed for developers who are looking to transition their projects from JavaScript to TypeScript smoothly and efficiently. TypeScript offers the benefits of static typing, enhanced tooling, and improved code maintainability, but migrating an existing codebase can be daunting, especially for large projects. In this workshop, participants will learn practical strategies and best practices for migrating from JavaScript to TypeScript incrementally, without resorting to using the "any" type everywhere. From setting up a TypeScript environment to gradually converting existing code to TypeScript, attendees will gain the skills and confidence to undertake successful migrations while maintaining code quality and minimizing disruptions to development workflows.


Introduction to TypeScript

  • Overview of TypeScript and its benefits
  • Understanding TypeScript's static typing system
  • Setting up a TypeScript development environment

Planning the Migration
