What is a closure package?Let's look at a piece of code first:function A () { var n = 0; function Inc () { n+ +; Console.log (n); } Inc (); Inc (); } //Take another look at the code: function A () { var n = 0; This function () { n+ +; Console.log (n); };

What is a closure package?Look at the code first:function A () { var n = 0; Function Inc () { n++; Console.log (n); } Inc (); Inc (); }a (); Console output 1, then output 2It's simple. Take another look at the code:function A () { var n = 0; This.inc = function () { n++; Console.log (n); };} var C = new A (); C.inc (); Console output 1c.inc

Background Due to the heart of openssl recently, I changed the ssl library 1.0.1g. I need to use this library to connect to the server. However, after I find that the Library is replaced, for some domain names, the ssl handshake will fail. In order to find out the cause of failure, we can find the handshaking status in the openssl tool.Tracking the ssl port of the Website 1. Tracking the handshake without any protocol parameters openssl s_client -connect gmail.com:443CONNECTED(00000003)depth=2 C

($ I = 0; $ I {Include $ files [$ I];}?>You can use the return statement to return a value in the files contained in the include () Statement in php3.0 and php4.0, and stop executing the content under the included file. However, php3.0 and php4.0 are different in handling such situations. In php3.0, the return statement cannot be included in {} unless it is in a function, because it indicates the return value of the function rather than the return value of the file. In php4.0, users can even re

value is greater than the current counter value of the table, the counter value of the table is set to this value. When inserting data, if the value of the specified auto_increment column is NULL or 0, mysql will allocate a value to the column from the counter, just like the value of this column that you did not specify. if the value of the specified auto_increment column is a negative number or exceeds the maximum value that the column can store, this behavior is not defined in mysql and may c
