day-string-from-numbers-array

day-string-from-numbers-array converts an array of weekday numbers to a string.

import { dayStringFromNumbers } from "day-string-from-numbers-array"

dayStringFromNumbers({
  daysArray: [0, 1, 6],
  sundayValue: 0,
  separator: ",",
  and: true,
})
//returns "Sunday, Monday, and Saturday"

dayStringFromNumbers({
  daysArray: [1, 6, 7],
  sundayValue: 7,
  separator: " |",
  and: false,

//returns "Monday | Saturday | Sunday"

dayStringFromNumbers Function

dayStringFromNumbers requires an object with the following properties:

Required Properties

daysArray and sundayValue are the only required properties.

Use sundayValue to indicate what number represents Sunday (a 0 or a 7).

daysArray must be an array of numbers that are valid for the sundayValue you've chosen.

export type WeekDayNumbersSunZero = 0 | 1 | 2 | 3 | 4 | 5 | 6
export type WeekDayNumbersSunSeven = 1 | 2 | 3 | 4 | 5 | 6 | 7

You can use the isValidDayStringDayNumbers function to prevent errors if you're using dynamic data that may have an array with invalid numbers included.

import { isValidDayStringDayNumbers } from "day-string-from-numbers-array"

const x = { daysArray: [0, 1, 2, 3], sundayValue: 7 }

const arePropertiesValid = isValidDayStringDayNumbers(x) // false

// prevent dayStringFromNumbers from throwing an error due to the invalid data (a 0 when daysArray should only contain numbers 1-7 due to sundayValue = 7)
if (arePropertiesValid) {
  dayStringFromNumbers(x)
}

Optional Properties

By default, multiple days will be separated by ", ". The final day in a list will be separated by " and " if there are 2 days or ", and" if there are 3 or more days.

import { dayStringFromNumbers } from "day-string-from-numbers-array"

dayStringFromNumbers({ daysArray: [1, 2, 3], sundayValue: 0 })
//returns "Monday, Tuesday, and Wednesday"
dayStringFromNumbers({ daysArray: [1, 2, 7], sundayValue: 7 })
//returns "Monday, Tuesday, and Sunday"
dayStringFromNumbers({ daysArray: [2, 3], sundayValue: 7 })
//returns "Tuesday and Wednesday"
dayStringFromNumbers({ daysArray: [7], sundayValue: 7 })
//returns "Sunday"

You can use the separator and and properties to change the string that separates dates and remove the " and " or ", and " from strings.

dayStringFromNumbers({
  daysArray: [1, 2, 7],
  sundayValue: 7,
  separator: " |",
  and: false,
})
//returns "Monday | Tuesday | Sunday"
