the reliability, consider all kinds of abnormal scenes; 4, with the ability to identify the risk level of the bug; ... wait a minute. Of course, it requires testers to have absolute familiarity with the product, more quickly to find the problem. Iv. testing does not guarantee quality Testers are not quality guards, testing will not improve quality, and will not reduce quality, good quality code is there, quality from the people who build the product, sounds incredible, but this is the heavy bur

language that is executed on the Web site user's computer, unlike server-side scripting, and thus poses a very low risk to the site itself. Some people think that Ajax programs can see the way its program logic and variable usage through the view of code, and increase the attack surface of the website, unlike the server-side program, can hide the program syntax. In fact, a safe site, the original must be in front of the data transmission to the back end, do a good job of filtering and

Ten, right? Let's try out and run the this code instead. Let Obs = rx.observable . Interval (+). publish () . RefCount (); SetTimeout (() = { //delay both subscriptions by 2 seconds obs.subscribe (v = console.log ("1st subscriber: "+ V)); SetTimeout ( //delay for a little more than a second and then add Second subscriber () = Obs.subscribe ( V = = Console.log ("2nd subscriber:" + V)), 1100); },2000); Interestingly we see exactly th
