An interview review: Exploring performance and data separation

Objective

More than half a year before there was an interview, just want to get a free ticket home, by the way to see luck

But I don't want that interview to benefit a lot, so it's okay to go out for interview The interview is helpful to the personal knowledge summary and the deepening of the thinking.

Deepening of course is not a matter of overnight, such as the interviewer asked me what is "performance and data Separation", on this issue I learned a long time ago, and many colleagues have discussed, but has not been a better result

Recently in the ipad related one-page application research, was a problem trapped thinking, Night saw two episodes, finished on paper painted, suddenly to more than half a year before a face test is a bit of thinking

So, this evening, take time to record, This article is only personal opinion, not necessarily correct, wrong please correct, time is too late, the wording is not clear do not blame

Interview Review

First of all, my resume was copied, there is a "separation of performance and data have a certain understanding", and then the interviewer asked about this

PS: NI, that is copied, I know he is dry God horse ...

To help me develop my thinking, the interviewer has a question:

He has a list of countries, now to place the list of countries in a, then B can be selected by a, or there can be a total list of options but B added, if a does not have to dynamically increase this item.

The problem came out, I now see that the interviewer wanted to ask the observer of the relevant knowledge, then did not understand ...

Now, say this problem and performance and data separation is not a problem, but not necessarily can make people very good association, so the answer to this question, or need to continue to dig

In fact, there are several solutions to this problem, even a beginner's friend can do, but to answer this question well we need to see behind the hidden intentions

For example, now is the operation B time need a and the linkage, if now out of a C or d???
