includes ( 'living', 30 )) // false See the code examples in this Codepen
const string = 'The greatest glory in living lies not in never falling, but in rising every time we fall.' // Check if it includes with `living` console. This position is from where it will start to look. includes ( 'Living' )) // false String includes with offset position parameter Īs the brothers startsWith() and endsWith(), this has another position parameter. So the following code will fail: const string = 'The greatest glory in living lies not in never falling, but in rising every time we fall.' // Check if it includes with `Living` console. It is important for the includes() function to know that it is a case-sensitive function. We can use the includes() function by calling it on a string and passing a substring to it: const string = 'The greatest glory in living lies not in never falling, but in rising every time we fall.' // Check if it includes with `living` console. To do so, we are using the JavaScript function includes(). While we recently checked if a string startsWith or a string endsWith a specific substring, today we will learn how to find out if a string includes another substring. Lets see how we can determine if a string contains a substring in JavaScript 10 May, 2020
