How to set an error of one character per line?

Question

JavaScript

Is there any pattern for searching in the form of a string. For example, let's take the string "elephant". It is
necessary to make it so that if the words "sloon" or "clone", etc., are in the database, with an error of one character, they are also displayed.
Can this be done through regular expressions or something else?
