How to convert day of week name to day of week number

Question

How can I get the integer equivalent of days of the week i.e monday to 2, tuesday to 3, wednesday to 4

Answer 1

Can use a lookup object:

var days = {
    sunday: 1,
    monday: 2,
    tuesday: 3,
    wednesday: 4,
    thursday: 5,
    friday: 6,
    saturday: 7
}

console.log(days["sunday"]) //1

Now, simply access any of the above properties and it's value will be the numeric day of the week!

console.log(days["monday"]) //2
