// GStrings (double quotes) support interpolation

// Interpolation is the act of replacing a placeholder in a string with a
// value when the string is evaluated. A placeholder is surrounded by ${}
// or prefixed with $.

def name = 'World'
println "Hello $name"

// There are also multi-line strings
def text = '''This is a long text that
spans multiple lines.'''

// ... and GStrings

name = 'user'
text = """Hello $name!

$text"""

println(text)
