From nine JavaScript gotchas, the following are nine traps that JavaScript is prone to mistakes. Although it is not a very profound technical problem, please note that it will make your programming easier, that is, make life easier. I will give some comments on some traps. Last commaFor exampleCodeNote that the last comma should be good in terms of Linguistics (this is allowed in Python's dictionary similar to data types ). Internet Explorer reports syntax errors, but it is not detailed. You

From nine JavaScript gotchas, here are nine pitfalls that JavaScript is prone to make mistakes. While not a very advanced technical issue, note that it will make your programming a little easier, known as making life easier. I will mix some comments on some pitfalls.1. Last commaAs in this code, note the last comma, which should be good in linguistics (Python's similar data type dictionary, dictionary, is allowed). IE will report grammatical errors, but vague, you can only scan from thousands of

long run, it is a profound knowledge to add linguistic features into the mystery of C + + and observe it. Now judge is a very simple thing, say what C + + sucks, design too bad and so on. When there is no understanding of the constraints on C + + design, many people blurt it out. Stroustrup (51CTO Editor's note: This Stroustrup is to invite the author to participate in the Stroustrup, that is, the C + + language designer Stroustrup) constraints are,

Perhaps this time, in fact, you run on this system application sucks cause of the problem.Next, what to do when memory is not available?It seems that we have analyzed a state where memory is not enough, that is, the large number of buffer/cache that are almost full of memory. But based on the Linux memory usage pr
