Improve readability

if( validScore(score) ) { ... } ^^^ why not use this (if readability and maintainance is the topic of concern) In case you need to maintain things or extrenaly change things or make things transparent - use a business rule engine or a business process engine. Again C# Version++ is inveting incompatible stuff, that make new code not work with old code. Very very Microsoft/Bad.

Interesting. Interesting as well the more the time pass the more python gains popularity, the more other language tends to have an approach of readability that you can find in AdaCore Embarcadero Technologies and PC SOFT . that's for good. c# is one of my favorite language, even if not the first.

💡 𝗖# 𝐓𝐢𝐩 - 𝗨𝘀𝗲 𝗔𝗻𝘆() 𝗺𝗲𝘁𝗵𝗼𝗱 𝗶𝗻𝘀𝘁𝗲𝗮𝗱 𝗼𝗳 𝗖𝗼𝘂𝗻𝘁() 𝗼𝗿 𝗟𝗼𝗻𝗴𝗖𝗼𝘂𝗻𝘁() 𝗺𝗲𝘁𝗵𝗼𝗱𝘀 🔥𝗖𝗼𝘂𝗻𝘁() and 𝗟𝗼𝗻𝗴𝗖𝗼𝘂𝗻𝘁() LINQ methods are used to check if the collection has at least one element. These methods enumerate the entire collection to compute the count. The same check is faster with the 𝗔𝗻𝘆() method as it avoids enumerating the collection. 📜 Rule ID: 𝗖𝗔𝟭𝟴𝟮𝟳 (Do not use 𝗖𝗼𝘂𝗻𝘁()/𝗟𝗼𝗻𝗴𝗖𝗼𝘂𝗻𝘁() when 𝗔𝗻𝘆() can be used) ❓Have you used 𝗔𝗻𝘆() instead of 𝗖𝗼𝘂𝗻𝘁()/𝗟𝗼𝗻𝗴𝗖𝗼𝘂𝗻𝘁() ? Comment below👇 ♻️ If this content is useful, 𝙧𝙚𝙥𝙤𝙨𝙩 to spread the knowledge. 👉 Please follow me (Poorna Soysa) and click the notification bell icon (🔔) on my profile to receive notifications for all my upcoming posts.
