String manipulation

• String interpolation:

var result = "The %s has defeated the %s in %s" % ["Player", "Boss", "Combat"]
print(result)
# Will prints:
# The Player has defeated the Boss in Combat

• Concatenate strings: var result = "Hello, " + "GDScript!"
• Format strings: var result = "Hello, %s!" % "GDScript"
• Split strings: var words = "Hello, GDScript!".split(", ")
