Variable Declaration issue
i am new to JS.
i did not undestand weather 'var' Keyword should be used or not when declaring variables. i already familier with php and there i will not use a 'var' for variable declaration. i like to program JS using similler PHP sysntax. so i code JS with out 'var' for varialb declarations and it works.
but can you please tell is it ok to declare variables with out the key word 'var'? if this is not good, then do all global and local variable declarations requir 'var'?
