Simple clean code #1

Change this:

if (user.active === true && user.age >= 18 && user.email !== null && user.email !== undefined && externalParams === true) return true;

To this:

const { active: userIsActive, age: userAge, email: userEmail } = user;



const minimalAge = 18;

const userAgeIsValid = userAge >= minimalAge;

const userHasConditionsToRegister= userIsActive && userAgeIsValid && userEmail && externalParams;



if (userHasConditionsToRegister) return true;

You might be thinking, "But you've increased the code by a lot, before, I only had one line!" And yes, you're absolutely right! However, fewer lines of code aren't always better than more lines.

When working with other developers and frequently maintaining the codebase, small details like the ones I've shown can make a big difference. In just a few seconds, anyone can understand the logic and rules behind the code. Additionally, if you need to add another condition, it becomes easy and clear to do so.
