The following functions can be used to manipulate and retrieve string details from objects and variables.
These should be written in the following formats:
variable.function(arguments), example - myVar.subStr(3,2) if your variable name was "myVar" and you wanted to use subStr() to find the 2 characters that begin 3 from the left.
object.function(arguments), example - city.coords.split(",") if you wanted to split the coordinates of your city into an array to determine the seperate x and y values using the split() function.
Click each function name in the table below for more details of it, with examples.
