Testing whether string starts with or end with another string

Posted by: admin November 30, 2017 Leave a comment

Questions:

How should I check whether a string starts or ends with a given string? There doesn’t seem to be any built-in methods available (or maybe it’s just the IDE I’m using that isn’t having it show up: RDE)

Answers:

There are built in methods:

"String".start_with? "S" # true
"String".end_with? "4" # false

Questions:
Answers:
string.start_with?("substring")
string.end_with?("substring")

Returns true or false
