Utility Library

This is a simple JavaScript utility library that provides common utility functions. The library includes functions for text manipulation, random number generation, object cloning, and function debouncing.

Functions

capitalizeWords(str)

Description:

Capitalizes the first letter of each word in a given string.

Parameters:

• str (string): The sentence to capitalize.

Returns:

• string: The sentence with the first letter of each word capitalized.

Example:

const result = capitalizeWords("hello world");
// Result: "Hello World"

getRandomInt(min, max)

Description:

Generates a random integer between the specified minimum and maximum values, inclusive.

Parameters:

• min (number): The minimum value (inclusive).
• max (number): The maximum value (inclusive).

Returns:

• number: A random integer between min and max.

Example:

const randomNumber = getRandomInt(1, 10);
// Result: a random number between 1 and 10

deepClone(obj)

Description:

Creates a deep clone of an object or array. This function is useful for copying complex objects without retaining references to the original.

Parameters:

• obj (object|array): The object or array to clone.

Returns:

• object|array: A deep copy of the input object or array.

Example:

const original = { a: 1, b: { c: 2 } };
const copy = deepClone(original);
// Result: { a: 1, b: { c: 2 } }

debounce(fn, delay)

Description:

Creates a debounced version of a function, delaying its execution until after a specified delay. This is useful for limiting the rate at which a function is called, such as in response to user input events.

Parameters:

• fn (Function): The function to debounce.
• delay (number): The delay in milliseconds after which the function will be called.

Returns:

• Function: A debounced version of the original function.

Example:

const debouncedFunction = debounce(() => {
    console.log("Function called!");
}, 300);

// The function will only be called 300ms after the last time debouncedFunction is invoked.

Usage

To use this library, simply import the functions you need and call them with the appropriate parameters.

import { capitalizeWords, getRandomInt, deepClone, debounce } from './your-library.js';

// Example usage:
const sentence = capitalizeWords("this is a test");
const randomNumber = getRandomInt(5, 15);
const clonedObject = deepClone({ name: "Alice", age: 25 });
const debouncedLog = debounce(() => console.log("Logged after delay"), 500);

debouncedLog();
