I have the following:
if (referrer.indexOf("Ral") == -1) { ... } What I like to do is to make Ral case insensitive, so that it can be RAl, rAl, etc. and still match.
Is there a way to say that Ral has to be case-insensitive?

Contains() method in C# is case sensitive. And there is not StringComparison parameter available similar to Equals() method, which helps to compare case insensitive.
Note that the Python string contains() method is case sensitive.
Both String#includes() and String#indexOf() are case sensitive. Neither function supports regular expressions. To do case insensitive search, you can use regular expressions and the String#match() function, or you can convert both the string and substring to lower case using the String#toLowerCase() function.
Add .toUpperCase() after referrer. This method turns the string into an upper case string. Then, use .indexOf() using RAL instead of Ral.
if (referrer.toUpperCase().indexOf("RAL") === -1) { The same can also be achieved using a Regular Expression (especially useful when you want to test against dynamic patterns):
if (!/Ral/i.test(referrer)) { // ^i = Ignore case flag for RegExp If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
