We can use the search() method with either a regular expression or string as an argument. This uses an expression to search for a match and returns the starting position of the desired word or substring.

How to find a position of a particular word or a substring in the given string? Var incStr = strng.includes('human', 38) Strng = 'Either way, time largely defines the human experience.'
