String.beginsWith(matchStr)

String.beginsWith(matchStr)

String.beginsWith() returns Boolean true if the chained string begins with a specific substring.

For example, if $MyString is "I do not like green eggs and ham":

$MyString.beginsWith("I do") returns true 

$MyString.beginsWith("Hello") returns false 

Also, with string literals:

("There are gentlemen now abed.").beginsWith("There are") returns true 

("There are gentlemen now abed.").beginsWith("Hello") returns false 

This operator searches for literal strings, not regular expressions. Matches are case sensitive

("There are gentlemen now abed.").beginsWith("there are") returns false 

See also String.endsWith(). If you need to search a String for a regular expression, use String.contains().
