Script Preparation code:

var today = new Date().getDay()

Tests:

const dayOfTheWeek = { 0: "Sunday", 1: "Monday", 2: "Tuesday", 3: "Wednesday", 4: "Thursday", 5: "Friday", 6: "Saturday", }; console.log( `What day of the week is today? ${dayOfTheWeek[today]}` );
Else If
let day; if (today === 0){ day = "Sunday"; } else if (today === 1){ day = "Monday"; } else if (today === 2){ day = "Tuesday"; } else if (today === 3){ day = "Wednesday"; } else if (today === 4){ day = "Thursday"; } else if (today === 5){ day = "Friday"; } else if (today === 6){ day = "Saturday"; } else{ throw new Error("Hey!
