output : true 1. This is an instance to use as a checker from the existing data. In this case, includes() method belongs to var str. As 'Geeks' string characters does exist on that var str, the outcome regarding this variable will output : true. Further info: Syntax:string.includes(searchvalue, start) Parameters Used: search value: It is the string in which the search will take place. start: Thi..
