js interprete concept.....

[dmjpro]

if i write ..... in suppose (C)

if(fun_call() == 100 || fun_cal() == 200)
{
//some code
}

then compiler during code generation ... it optimizes ... like

int i = fun_call();
if(i == 100 || i == 200)
{
//some code
}

then the overhead of twice function call removed.....

now my question is....

is this true for JS?????
we know that js interpreted.....

if i write something like this is JS then is it optimized as in other languages,
or it slows down the executing performance?????

i know JS is scripting language .....
i think it is a bad programming practice..... m i right?????

plz help me out ... thanxxxx in advance

I'm unsure about the inner workings, but I would assume that it could be optimized. There are optimization tools that reduce the size of the code and can improve performance.
