In JavaScript, How Can I Verify If A Value Is Included In An Array?

To check if an array includes a specific value in JavaScript, you can use the includes() method.

Here’s an example:

let array = [1, 2, 3, 4, 5];

console.log(array.includes(3)); // Output: true
console.log(array.includes(6)); // Output: false

In the above code, we have an array array that contains numbers from 1 to 5. We use the includes() method to check if the array includes the values 3 and 6. The first console.log() statement returns true since the value 3 is present in the array, whereas the second console.log() statement returns false as the value 6 is not present in the array.
