When you see commented-out code, delete it ❌

Don’t worry, the source code control system still remembers it.

If anyone really needs it, he or she can go back and check out a previous version.

Don’t suffer commented-out code to survive❗️

Dead Functions 💀

Methods that are never called should be discarded. ❌

Keeping dead code around is wasteful.

Don’t be afraid to delete the function.

Remember, your source code control system still remembers it.

Eval 👾

if you know about the dot notation, but are ignorant of the subscript notation, you might write:

eval("myValue = myObject." + myKey + ";"); 

〰 instead of :

myvalue = myObject[myKey]; 

The eval form is much harder to read.
This form will be significantly slower because it needs to run the compiler just to execute a trivial assignment statement ❗️

What is Unit Test ❓

A unit test is a piece of a code (usually a method) that invokes another piece of code and checks the correctness of some assumptions afterward. ✅

If the assumptions turn out to be wrong, the unit test has failed. ❌

A unit is a method or function.

#UnitTest
@ProgrammingTip

Properties of a good unit test ✅

A unit test should have the following properties :

1️⃣ It should be automated and repeatable.

2️⃣ It should be easy to implement.

3️⃣ It should be relevant tomorrow.

4️⃣ Anyone should be able to run it at the push of a button.

5️⃣ It should run quickly.

6️⃣ It should be consistent in its results.

7️⃣ It should have full control of the unit under test.

8️⃣ It should be fully isolated (runs independently of other tests).

9️⃣ When it fails, it should be easy to detect what was expected and determine how to pinpoint the problem.
