|
|
<p><a href="https://en.wikipedia.org/wiki/Programming_idiom">Idioms</a> are commonly used
|
|
styles and patterns largely agreed upon by a community. They are guidelines.
|
|
Writing idiomatic code allows other developers to understand what is happening
|
|
because they are familiar with the form that it has.</p>
|
|
<p>The computer understands the machine code that is generated by the compiler.
|
|
The language is therefore mostly beneficial to the developer.
|
|
So, since we have this abstraction layer, why not put it to good use and make
|
|
it simple?</p>
|
|
<p>Remember the <a href="https://en.wikipedia.org/wiki/KISS_principle">KISS principle</a>:
|
|
"Keep It Simple, Stupid". It claims that "most systems work best if they are
|
|
kept simple rather than made complicated; therefore, simplicity should be a key
|
|
goal in design, and unnecessary complexity should be avoided".</p>
|
|
<blockquote>
|
|
<p>Code is there for humans, not computers, to understand.</p>
