It is important for a programmer to be lazy.

Why do people live ??
Rello said that people live to eat!
For a NLE ProgramFor those who come to dinner, a project is usually not 100 or 200 rows CodeA lot of code is required to form a software.
If the same AlgorithmEach place I use less code than you, so if there are ten places that use this algorithm, then I will use 10 rows and one hundred rows less than you, and then I will be more efficient than you, the promotion is definitely faster than you, and the salary is definitely more than you.
So laziness is an important programming method,
There are many ways to be lazy: Try to call a function in the same place, and never use case in static places where dynamic processing can be separated. but lazy has to have a premise, to achieve the same effect, you must find the best way to achieve the same effect. That is to say, you must carefully consider it.
It's also easy to say, so it's not easy to say. Maybe everyone will understand it slowly.
