String Text Splice

[s.long]

Hello, is there a way to splice a text similar to javascript:

def string = ‘ThisString’;
println(string.slice(0,4));

expecting ‘This’ to be returned

Error:

[Marek_Melocik]

def string = ‘ThisString’;
println(string.substring(0,4));

[s.long]

Thank you - your method worked!
