Strings ​

Text strings represent sequences of characters, such as names, descriptions, messages, or any other type of textual information. In JavaScript, text strings are delimited by single ( ' ) or double ( " ) quotes. More information in this guide

Booleans (true and false) ​

Booleans represent logical values of true or false. They are essential for making decisions in your code and controlling the execution flow of your application.

Objects ​

An object is a data structure that stores information in key-value pairs. Each key is a unique identifier (a string) that points to a value, which can be of any data type (number, string, array, another object, etc.).

How to identify an object? ​

  • It is written inside {} (curly braces).
  • Uses key-value pairs separated by colons :.
  • Keys are strings.
  • Values can be any data type.

Creating an object ​

You can create an object using curly braces {} and separating properties with commas. Each property has a key (name) and a value, separated by a colon :. For example:

javascript
const person = {
  name: 'John',
  age: 30,
  city: 'Madrid',
}; // Object created with name, age and city properties

return person;

You can check if a value is an object using:

javascript
return typeof person; // "object"

Accessing properties: ​

You can access the value of a property of an object using dot notation.

Modifying properties: ​

If you need to change the value of an existing property, you can assign a new value to its key. For example:

javascript
person.age = 31; // Updates the value of the property "age" to 31

Adding properties: ​

You can add new properties to an object by assigning a value to a new key. For example:

javascript
person.profession = 'Developer'; // Adds the property "profession" to the object

Arrays ​

An array is a data structure that stores multiple values in an ordered list. Each value is assigned a numeric index, starting from 0.

How to identify an array? ​

  • It is written inside [] (square brackets).
  • Elements are separated by commas.
  • The order of elements is maintained.

Creating an array: ​

To create an array, use square brackets [] and separate the elements with commas. For example:

javascript
return (myShoppingList = ['apples', 'milk', 'eggs', 'bread']);

Accessing elements: ​

You can access a specific element in an array by using dot notation.

Modifying elements: ​

You can change the value of an existing element in an array by assigning it a new value using its index. For instance:

javascript
myShoppingList[1] = 'yogurt'; // Replace "milk" with "yogurt"

Types of content in an array ​

Arrays can contain different types of values, including:

  • Numbers: [1, 2, 3]
  • Strings: ["apple", "banana", "cherry"]
  • Booleans: [true, false, true]
  • Objects: [{name: "Alice"}, {name: "Bob"}]
  • Other arrays (Nested Arrays): [[1, 2], [3, 4]]
