Answer

To check if a specified element is present in an array in JavaScript, you can use methods like includes.

✐ Examples

1 Check if Element 30 is present in Integer Array using includes

In this example,

We create an integer array named numbers with values 10, 20, 30, 40, 50.
We use the includes method to check if element 30 is present in the array.
The includes method returns true if the element is found, otherwise false.

JavaScript Program

const numbers = [10, 20, 30, 40, 50];
const isPresent = numbers.includes(30);
console.log(`Element 30 is present: ${isPresent}`);

Output

Element 30 is present: true

2 Check if Element 60 is present in Integer Array using includes
