javascript - 0 + integer is weird in JS -


this question has answer here:

go browser's js console , try these:

-14 // -14  -014 // -12  -24 // -24  -024 // -20  -0024 // -20  012 // 10

why 0-integer construct giving me results 2 smaller in absolute value?

"never write number leading 0 (like 07). javascript versions interpret numbers octal if written leading zero." (see: http://www.w3schools.com/js/js_numbers.asp)
