It’s clean and well written, and I love that it has examples.\nFor anyone coming into the industry, use the tips not as “rules” but “guidelines”. Also expect a lot of the recommendations to be crushed in mature codebases - things let real messy, real fast.\nI’ll call out a couple of things:\n\n\nSingle Responsibility Principle and limiting function length are good guides, but too many people are dogmatic about them. Approach them pragmatically and think about what makes sense in terms of overall application complexity and readability. You don’t always need to adhere to SRP, and longer can be more readable then multiple smaller functions that are called out to.\n\n\nCode comments. I will die on the hill of “write MORE code comments”. AND maintain them. Professional programmers are in the business of communicating with other people (through code). You don’t write code for a compiler - you write it for fellow developers. Comments are golden nuggets for future programmers. And if I hear one more person talk about “self documenting code”… 😠\nIs writing good comments hard? Yes. But no harder than anything else we have to do as developers if we want to do our jobs well. If you don’t like hard or effort then I suggest a different career.\n\n\nUnit tests are good, but in your average business setting, damn are they hard to do and maintain (assuming you have time for them). What I wish I would see developers do is more manual testing as they develop. That also requires you to better understand the larger product and domain. Don’t be shy to test it end-to-end.\n\n\nOverall, thumbs up to this article.","datePublished":"2024-11-07T01:41:28.378Z","url":"https://daily.dev/posts/QFOywYsuS#c-bbZ6QKddM","author":{"@type":"Person","name":"Jason","url":"https://daily.dev/jsnelders","image":"https://media.daily.dev/image/upload/s--O0TOmw4y--/f_auto/v1715772965/public/noProfile"},"interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":7}},{"@type":"Comment","text":"As a software developer i know how it is important … when i read someone code who don’t follow SOLID approach , it is very painful to read them","datePublished":"2024-11-06T16:53:45.262Z","url":"https://daily.dev/posts/QFOywYsuS#c-bKzxLbLs0","author":{"@type":"Person","name":"Harshjeet","url":"https://daily.dev/harshjeet","image":"https://media.daily.dev/image/upload/s--ul_0cjhX--/f_auto/v1757478847/avatars/avatar_eMl6GJBOrjB78Eq9RKNc8?_a=BAMClqZW0"},"interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":7}},{"@type":"Comment","text":"Love it!","datePublished":"2024-11-06T09:47:42.183Z","url":"https://daily.dev/posts/QFOywYsuS#c-kwV3wQqfk","author":{"@type":"Person","name":"Francis Hong","url":"https://daily.dev/francishong1991","image":"https://lh3.googleusercontent.com/a/ACg8ocJKCILukJuvn6EhhG6vGEQ74jFONNhZRaImYs808UMnXNRi9pA=s96-c"},"interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":5}},{"@type":"Comment","text":"thanks… great post…","datePublished":"2024-11-06T16:42:49.368Z","url":"https://daily.dev/posts/QFOywYsuS#c-KrjF0Owwa","author":{"@type":"Person","name":"Jose Obeso","url":"https://daily.dev/joseobeso","image":"https://lh3.googleusercontent.com/a/ACg8ocI4izLtuxQYkor9Ga6EOeodUTvUgXQnIgWkY9iRnDC8ALL8AQ7O=s96-c"},"interactionStatistic":{"@type":"InteractionCounter","interactionType":{"@type":"LikeAction"},"userInteractionCount":3}}]} ```
