Extensions

The Extensions module provides a way to extend the functionality of standard JavaScript types.

Array

• shuffle() - Shuffles the elements of an array randomly.
• clone() - Creates a shallow copy of the array.
• unique() - Returns a new array with unique elements from the original array.
• pack() - Packs the array, remove empty elements.

let arr = [1, 2, 3, 4, 5];
let shuffled = arr.shuffle();
console.log(shuffled); // Random order

Number

• format() - Formats a number with specified decimal places and thousands separator.

let num = 1234567.89;
let formatted = num.format(2, ".", ",");
console.log(formatted); // "1,234,567.89"

String

• toArray() - Converts a string to an array of characters.

This method is useful for manipulating strings as arrays. Method has a lot of arguments:

  "...".toArray(
      delimiter = ',',
      type = 'string',
      format = '',
      locale = 'en',
      pack = false
  );

• delimiter - by which character to split the string
• type - type of values in returned array: string, number, float, int, integer, date and boolean
• format - format of the value in the array. Used with date type: YYYY-MM-DD
• locale - locale for the date format. For example, en for English
• pack - if true, remove empty elements from the array

let str = "Hello, world!";
let arr = str.toArray();
console.log(arr) // ["Hello", "world!"]
