Answer 3

sorry guys I mix code I want to know about this code

Answer 4

i=0 x=1
i=1 x=2
i=2 x=4
i=3 x=7
i=4 x=11
i=5 x=16
i=6 and that's it, because 6 is not less than 6, its equal :) so x is 16 :)

Answer 5

yes but this code I meet in javascript question here)) lol

Answer 6

I understand ok

Answer 7

I deleted the code because don't look which in code two x but thx guys

Answer 8

this code will add each i from 0 to 5 to x that is already set to 1.
so x will be 16. if you wanted to do this then your code is ok

Answer 9

@Kristina
that code will create infinite loop of doing nothing. because var i is incrementing and x stays 1 and will never get >= 10. however, there is no code betw parentheses so it will do nothing - forever

Answer 10

x will increment 9 times bcz of loop, and will become 10.
so x+=x+100 is x=x+x+100
which means x is 120
