Discussion on: 5 Tips to Write Clean Code in JavaScript

Hey Simon, nice article! Dev.to recommended it to me and I really enjoyed the read. Very well written and good points raised.

To foment the discussion, I'd like to point out something

1. Nested if statements and switch cases

• The good part
  • Switch cases are way more readable than if's statements when we're talking about multiple conditionals.

• The problems
  • There are are a lot of problems with switch statements, and a lot of people smarter than me have proved that. Instead of giving you some quotes, I'll drop the entire article because to me these are must read.
  • What’s wrong with the switch statement in JavaScript?
  • Don't use switch

• The solution
  • Object literals! They are as readable as switch statements. You can be as creative as you want with them, so you're not forced to break any pattern or standard.

Instead of

switch (dayOfTheWeek)) {
  case 0:
    day = "Sunday";
    break;
  case 1:
    day = "Monday";
    break;
  case 2:
    day = "Tuesday";
    break;
  case 3:
    day = "Wednesday";
    break;
  case 4:
    day = "Thursday";
    break;
  case 5:
    day = "Friday";
    break;
  case 6:
    day = "Saturday";
    break;
  default: 
    throw new Error("Hey! We have only 7 days in the week");
}

How about

const dayOfTheWeek = {
  0: "Sunday",
  1: "Monday",
  2: "Tuesday",
  3: "Wednesday",
  4: "Thursday",
  5: "Friday",
  6: "Saturday",
};

console.log('day of the week:', dayOfTheWeek[new Date().getDay()]);
