Discussion on: 10 Clean code examples (Javascript).

View post

I think clean code is still a very debatable topic. To me, personally, clean code is code with improved readability or improved contextual information:

Example:

const g  = 9.81 // unclear
const GRAVITY_OF_EARTH = 9.81 // clear

Same goes for preparing structures for commenting code:

hard to read

if (condition) {
  // long block comments about 
  // what this branch actually does
  ...
} else {
  // long block comments about 
  // what this branch actually does
  ...
}

easier to read:

// long block comments about 
// what this branch actually does

if (condition) {
  ...
}

// long block comments about 
// what this branch actually does

else {
  ...
}
