'What does '/in/' do in javascript [duplicate]
After searching for 'working onload event' I found Abhishek's anwser which used /in/ and after that, I tried searching for it but couldn't find anything useful about it, does someone know what does it do?
Solution 1:[1]
Without more context, /in/ looks like a regular expression (as mentioned by VLAZ), which you can learn more about here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Guide/Regular_Expressions
I also like https://regex101.com/ for help reading or writing complex regular expressions. Just make sure to select the Javascript "flavor" as different languages implement regular expressions differently.
