After reading the docs at https://docs.toit.io/language/strings I don't understand the way to do string contains. In Python:

if "foo" in "foobar":
    print("String was contained")

Ruby:

if my_string.include? "foo"

Is there a way to check to see if a string contains a substring?

thanks! @kasperl

"foobar". contains "foo"

yep, that worked.

👍

Also useful:

index := haystack.index_of needle
  // If it's not there, then index is -1:
