JS Switch

Relax. We'll talk through this in plain words — no textbook voice.

switch statement is used to pick and run one of several cases based on a variable's value. if...else if...else can replace a long chain of these.

javascript

const day = new Date().getDay(); // Sunday = 0, Monday = 1, ...
let dayName;

switch (day) {
  case 0:
    dayName = "Sunday";
    break;
  case 1:
    dayName = "Monday";
    break;
  default:
    dayName = "Another day";
}
console.log("Today is " + dayName);

(Depends on the day you run it) Today is Friday
