When can I use “switch case” statements?

When you have to compare a single value against many different values and then perform different actions based on the value.

let day = "Friday"

switch(day.toLowerCase()) { 
    case "monday": console.log("Go run")
    break;
    case "tuesday":
    case "wednesday":
    case "thursday": console.log("work work")
    break;
    case "friday": console.log("party")
    break;
    default: console.log("Meditate")
}
// party
