(++a = 6) * (a++ = 7) = 42

@scott i understand how ++a is 6 but a++ should be 6 as well because a++ evaluates first then it increments.so i think answer should be 36=6*6

@Nitish, i had an answer for you before i saw you had a c++ tag for this. I don't know if you know this is a JavaScript q&a.

My new answer is if this was c++ your answer 36 would probably be correct. If JavaScript, then it's syntactically written incorrectly so it would (and did) console.log() to 36.

++a=6..it will Increment the value of a=5...then a++=7..because this will increment the value of a..which was incremented before(a=6)

a++ will be 6 because it will execute first then incremental like if i=5 j=i++ then i=6 and j=5
