Use JavaScript methods on variables
Lombardi variables are JavaScript objects, which enables you to use standard JavaScript methods on Lombardi variables. The methods used must correspond to the variable type.For example, you can call the toUpperCase() or toLowerCase() JavaScript method on a Lombardi variable of type String. In the following example, the results of the call are used to assign a new value to the variable:
tw.local.myString = tw.local.myString.toUpperCase()
