In TypeScript, How Can I Determine If A String Is Present In An Array Using JavaScript?

In TypeScript, the includes() method can be used to check whether an array contains a specific string. Here’s an example:

const array: string[] = ["apple", "banana", "orange"];

const containsOrange: boolean = array.includes("orange");
console.log(containsOrange); // output: true

const containsPineapple: boolean = array.includes("pineapple");
console.log(containsPineapple); // output: false

In this example, the includes() method is called on the array variable with the string to be checked as the argument. It returns true if the string is found in the array, otherwise it returns false.
