I am scripting automation in Javascript, using jest and puppeteer right now, and I want to verify a name, for example;

I have a name of const name = Watson, James R. and wanted to compare the name const info_name = Watson James , which we can hypothetically say that they are the same person. When I was using python and selenium I usually use, in just to check the presence of a letter or word inside a string or list, so my question is, what is the best function I can use?

I saw the use of .includes but it is too "case sensitive" one different character and it gives off "False" result. Also I saw .some but I get an error of ".some is not a function".

What can I use for alternatives? I would gladly appreciate your replies, Thank you in advance!

  • You mean you want to check if substrings of info_name (e.g. "Watson") are contained in name? Commented Aug 8, 2021 at 16:14

    What you explain sounds like a case insensitive, fuzzy search. I don’t think this exists in js. Can you post examples of what should match and what shouldn’t? Commented Aug 8, 2021 at 16:15

The equivalent of in with JavaScript is .includes.
In order to ignore case sensitivity you can convert both strings to lower case with .toLowerCase() and then apply .includes.

console.log(string.toLowerCase().includes(substring.toLowerCase()));
