DeclareVariable() private method

Declares a variable or function in this scope. This will be initialized with the value of the given expression.
private DeclareVariable ( string name, Jurassic.Compiler.Expression valueAtTopOfScope = null, bool writable = true, bool deletable = false ) : DeclaredVariable
name string The name of the variable.
valueAtTopOfScope Jurassic.Compiler.Expression The value of the variable at the top of the scope. /// Can be null to indicate the variable does not need initializing.
writable bool true if the variable can be modified; false /// otherwise. Defaults to true.
deletable bool true if the variable can be deleted; false /// otherwise. Defaults to true.
