During my initial foray into TypeScript, a chance opportunity allowed me to showcase my contract interaction code in a group focused on front-end and Blockchain development. Coincidentally, I noticed an older developer next to me grappling with the complexities of JavaScript, his console filled with error messages.

I took the initiative to help migrate his project to TypeScript. By leveraging the powerful features of TypeScript, such as generics, type guards, interfaces, enums, and strict mode, I successfully added a layer of security to his code. This not only improved the reliability of the code but also significantly reduced potential errors.

Surprisingly, this developer is in awe of the power of TypeScript, lamenting that this programming method is even more secure and reliable than writing a white paper.

In the following two years, I continued to participate in maintaining this project. In 2020, this developer decided to retire and surprisingly proposed to gift me a small apartment he owned in Shenzhen. As a 19-year-old, I was shocked by this generous offer, and even momentarily lost my composure, leading to a compilation error.

Although I declined this generous gift, the wise developer left a thought-provoking remark: 'Young people, remember that type safety is indeed important, but on-chain security is even more crucial. However, true security often comes from having your own place.'

This experience not only showcases the advantages of TypeScript in improving code quality but also reflects the intergenerational mutual assistance and friendship within the tech community. It reminds us that while pursuing technological advancement, we should also pay attention to individual long-term development and life security.
