The includes() method returns a boolean value (true or false) indicating whether the element exists in the array or not. This code will output the following: Found green at index 1 const colors = Ĭonsole.log(`Found $`) Ĭonsole.log(foundColors) // Output: If you need to search for multiple elements, you can use a for loop to iterate over the array and check each element using one of the above mentioned methods. You can also pass a second argument to the indexOf() method to specify the index at which to start the search.įor example: const colors = Ĭonst index = colors.indexOf('green', 2) The indexOf() method of the Array object returns the index of the first occurrence of the element in the array or -1 if the element is not found.
