ESLint coding standards are an important part of modern programming, especially when working with JavaScript or TypeScript. In my experience, I find ESLint very useful overall. It helps keep code clean, organized, and easier to read. However, I also think that sometimes it can feel a little too strict about small details that may not be the most important issues in a program.
One of the biggest benefits of ESLint is consistency. When multiple programmers work on the same project, everyone may have different habits. Some people use double quotes, others use single quotes. Some people use extra spaces, others don’t. ESLint forces everyone to follow the same rules. This makes the code look uniform and professional.
For example, ESLint might require single quotes instead of double quotes:
// code ex.
In this case, both versions work exactly the same. The program will run without problems either way. That is why sometimes these rules can feel unnecessary. Whether we use single or double quotes does not change how the program functions. It only changes how it looks.
Another example is extra blank lines at the end of a file. ESLint may complain if there are too many empty lines:
// another code ex image
Even though the code works perfectly fine, ESLint might warn that there are too many blank lines. Fixing this does not improve performance or logic. It only improves formatting. Sometimes it feels like time is being spent fixing small formatting issues instead of focusing on bigger programming problems.
However, even though some rules may seem minor, I still believe ESLint is very helpful. Clean and organized code is easier to read and maintain. For example, consistent indentation and spacing make a big difference:
// code ex. image:
The second version is much easier to read. When projects become large, readability becomes extremely important. Other programmers need to understand the code quickly. ESLint helps enforce these formatting rules automatically, which saves time in the long run.
Another important benefit is catching real errors. ESLint does not only check formatting. It can also warn about unused variables or possible mistakes:
// code ex. image
If result is never used, ESLint will give a warning. This helps programmers clean up unnecessary code and avoid confusion.
In conclusion, I believe ESLint coding standards are very useful overall. They help improve cleanliness, organization, and teamwork in programming projects. At the same time, I think some rules can feel too strict or overly focused on small details like quotation marks or blank lines. Even so, the benefits of having consistent and readable code outweigh the minor frustrations. ESLint may sometimes feel picky, but it ultimately helps programmers write better and more professional code.
