Answer 1

First of all you should know the following 5 falsy value which is considered as false in condition.
1. 0. //Zero
2. "" //Empty string
3. null
4. NaN
5. undefined

Second :
1 :
c=(a&&b) , in and logical operation if the first value is not a falsy value then it goes to check the second one.
2:
C=(a||b), in or logical operation if the first value is not a falsy value it will not check the second value , whenever the first value is a falsy value the program will check the second one.
