The code location file is global.js under jq
Let me talk about the role and purpose of noConflict.
**
The role of the noConflict method is to cancel the pointing, because the pointing is cancelled in JQ, because in JQTake cancellation refers to , because as in J Q in is an alias JQ, and we may use other js library included in the actual development of jq, and these may also use the libraryas a variable of one of their exposed , And no C onflict is to solve this problem. By using no C onflict, we can cancel the variables exposed as one of them in JQ, and noConflict is to solve this problem. By using noConflict, we can cancel JQAs is his who 's a Yi a storm exposed out to the variable amount , while the n- O C O the n- f L i c t would be as a solution depends which one to ask questions . Pass through so that using n- O C O n- F L I C T , I can to take eliminate J QIn point.

Next, explain the structure of the code
**
In the source code, we can see that at the beginning of the code, the $sum jQueryattribute in the window will be assigned to the private variable $and jQuery, and then in the noConflict method, window.$ === jQuerythe judgment will first be judged to verify whether the jq is introduced in the project Renamed $, if renamed, then assign the new $value to window.$. Specifically, if you $use other js libraries in addition to JQ $, then I will give the location to other js libraries, $and finally return jQueryload JQ by letting you re-declare a variable name, instead of passing it $.
In the second judgment, deep && window.jQuery === jQueryit is to iterate the JQ version. Two different JQ versions may be used. If iteration is required, the deep value is true.
