Javascript Functions Development Tutorials, Guides & Insights

• Bracket notation:

    console.log(person["age"]); // 25

Let’s start with a simple script that displays a message in the browser’s console.

console.log("Hello, World!");

However, there are situations where you might want to control or change the value of this, and that's where call, apply, and bind come into play.

The call method allows you to invoke a function with a specified this value and arguments passed individually.

Lodash is one of the most popular JavaScript utility libraries, offering a wide range of functions for common programming tasks such as working with arrays, objects, and strings.

<table>
  <tr>
    <th>Function</th>
    <th>Description</th>
    <th>Example</th>
  </tr>
  <tr>
    <td><code>_.chunk(array, size)
    Splits an array into groups of the specified size.
    _.chunk(['a', 'b', 'c', 'd'], 2) => [['a', 'b'], ['c', 'd']]
  
  
    _.debounce(func, wait)
    Creates a debounced function that delays invoking the provided function until after the specified wait time.
    _.debounce(() => console.log('Hello'), 1000)
  
  
    _.cloneDeep(value)
    Creates a deep clone of the provided value.
    _.cloneDeep({ a: 1, b: { c: 2 } }) => { a: 1, b: { c: 2 } }
  
  
    _.merge(object, sources)
    Merges two or more objects into one, combining their properties.
    _.merge({ a: 1 }, { b: 2 }) => { a: 1, b: 2 }
  
  
    _.uniq(array)
    Creates a duplicate-free version of an array.
    _.uniq([1, 2, 2, 3, 4, 4]) => [1, 2, 3, 4]
