Very worth reading
You have concisely, clearly and thoroughly explained the differences between local and global variables.Some other tutorials I have read are inconsistent with their presentation of local and global variables, which serves to create more confusion and frustration.
One tutorial mentioned that you can declare a local variable within a function without using the var keyword.Is that possible? My understanding is, and verified by your tutorial, is that whenever a variable is declared within a function without using the var keyword, then it should always be considered as being global.In essence then, a variable is local within a function only if, it is preceded with the var keyword such as: var sky = 7; without the var keyword, a variable declared within a function should always be considered a s being global. Is that correct?
for the nice tutorial
