Here's a neutral and interesting summary of the text: SonarLint has identified assignments within sub-expressions as its number one issue in TypeScript projects, due to their potential to cause hard-to-spot bugs. This issue can be particularly challenging to identify, especially in more complex codebases, but is often caught by testing, linting, or tooling like SonarLint. In addition to this issue, SonarLint has also identified other common problems in TypeScript projects, including optional property declarations, creating and dropping objects immediately, unused local variables and functions, non-empty statements, and assignments within sub-expressions that affect readability. By using SonarLint, developers can avoid these issues and write more robust and maintainable code.
