variables is much slower than local variables. But this usage ensures that our variables must be global variables. In addition, in order to ensure the speed, we use the global variable, we can define a local variable Var, and then give the global variable, so you can get a global variable local reference. 1.2 Variable types There are no defined variables, the type is undefined. The value of a variable can be a function. A function can act as a role in a class in

For now, this: Foo.tostring () ==> foo+ "" It is also possible to foo.tostring () this usage, but there are some people insecure situations that need to be added to some optimizations such as: foo+ "" --max-line-len (default 32K characters)-add a newline after around 32K characters. I ' ve seen both FF and Chrome croak when all the code is on a single of around 670K. Pass–m
