Video tutorials are very easy to follow, productive and easy to grasp. The only problem I find with video tutorials is, when you get stuck or have some doubt few days after watching the tutorial, it’s hard to refer back. So, its always good to prepare some notes of important points which you can refer back easily. I’m going to share my notes here as I go along, I hope you find it use full.
Some Correct variable names
Wrong variable names
1user, user-name,user name
Variable names like var1,var2 are correct but not advised to be used as when you look back the back after some days you may not understand what var1 or var2 means. It’s advised that you use some meaning full user names like catName, place,gender.
In the above code the lines 2 and 3 are together equivalent to line 4.
In my next post I will write about operators and events, stay tuned.
