💼 Career

Knowing arrays is essential for any programming job because they help manage collections of data efficiently.

1

Create the initial array

Create an array called fruits with these exact values: 'Apple', 'Banana', and 'Cherry'.

Javascript

// Create the array fruits with 'Apple', 'Banana', and 'Cherry'
// Your code here

Need a hint?

Use square brackets [] to create an array and separate items with commas.

2

Add a new fruit variable

Create a variable called newFruit and set it to the string 'Orange'.

Javascript

const fruits = ['Apple', 'Banana', 'Cherry'];
// Create newFruit and set it to 'Orange'
// Your code here

Need a hint?

Use const newFruit = 'Orange'; to create the variable.

3

Add the new fruit to the array

Use the push method on the fruits array to add the newFruit variable.

Javascript

const fruits = ['Apple', 'Banana', 'Cherry'];
const newFruit = 'Orange';
// Add newFruit to fruits array
// Your code here

Need a hint?

Use fruits.push(newFruit); to add the new fruit.

4

Display the fruits array

Write console.log(fruits) to print the fruits array and see all the fruits.

Javascript

const fruits = ['Apple', 'Banana', 'Cherry'];
const newFruit = 'Orange';
fruits.push(newFruit);
// Print the fruits array
// Your code here

Need a hint?

Use console.log(fruits); to show the array in the console.
