Functions

1. Array Utilities

removeDuplicates(arr)

Removes duplicates from an array.

• Parameters:

  • arr (Array): The array from which duplicates will be removed.

• Returns: A new array with unique values.

Example:

const { removeDuplicates } = require('my-dev-utils').arrayUtils;

const arr = [1, 2, 2, 3, 4, 4, 5];
console.log(removeDuplicates(arr));  // Output: [1, 2, 3, 4, 5]

groupBy(arr, key)

Groups an array of objects by a specific key.

• Parameters:

  • arr (Array): The array of objects to be grouped.
  • key (string): The key to group by.

• Returns: An object where each key is the value of the specified key in the original objects, and the values are arrays of objects that share the same key.

Example:

const { groupBy } = require('my-dev-utils').arrayUtils;

const objects = [
{ id: 1, category: 'A' },
{ id: 2, category: 'B' },
{ id: 3, category: 'A' },
];
console.log(groupBy(objects, 'category'));
// Output: { A: [{ id: 1, category: 'A' }, { id: 3, category: 'A' }], B: [{ id: 2, category: 'B' }] }

2. Date Utilities

formatDate(date, formatString = "dd/MM/yyyy")

Formats a date using the given format string.

• Parameters:

  • date (Date | string): The date to be formatted.
  • formatString (string): The format string (default is "dd/MM/yyyy").

• Returns: A string representing the formatted date.

Example:

const { formatDate } = require('my-dev-utils').dateUtils;

const formattedDate = formatDate(new Date(), 'yyyy-MM-dd');
console.log(formattedDate);  // Example output: 2024-11-12

daysBetween(date1, date2)

Calculates the number of days between two dates.

• Parameters:

  • date1 (Date | string): The first date.
  • date2 (Date | string): The second date.

• Returns: The number of days between the two dates.

Example:

const { daysBetween } = require('my-dev-utils').dateUtils;

const days = daysBetween('2024-11-10', '2024-11-12');
console.log(days);  // Output: 2

3. UUID Utilities

generateUUID()

Generates a unique identifier (UUID).

• Returns: A string representing the generated UUID.

Example:

const { generateUUID } = require('my-dev-utils').uuidUtils;

const uuid = generateUUID();
console.log(uuid);  // Output: 'e1b0f459-f56b-4d5e-b083-0813214e6b06'

generateAlphanumericId(length = 8)

Generates an alphanumeric identifier of a given length.

• Parameters:

  • length (number): The length of the identifier (default is 8).

• Returns: A string representing the alphanumeric identifier.

Example:

const { generateAlphanumericId } = require('my-dev-utils').uuidUtils;

const id = generateAlphanumericId(10);
console.log(id);  // Output: 'jX7V4BZs93'

4. String Utilities

capitalize(str)

Capitalizes the first letter of a string.

• Parameters:

  • str (string): The string to be capitalized.
