Running well, isn't it? But one day it does not work, and the returned value is Nan ,. Only a library is introduced. It turns out that this library has rewritten the prototype of array. In this way, our arr has no more attribute (method) than that of... in... it will be traversed. Therefore, this is safer:

explain to Jin: Even if your controls use events to strip the work of some business logic, the business logic is coupled with data, so what do you use to let the business logic know your data structure? Array? Datareader? Dataset?

very good language to look forward to.----------------------------------------------------------------------The struggle for language is time-consuming, and there is no need to talk to these people. Everyone has their own preferences, some people on the Java call, some people do not like go, you say nothing is useless.

The descendant selector sucks.
Not only is the performance low and the code is very fragile, HTML code and CSS code is seriously coupled, the HTML code structure changes, CSS also have to modify, this is how bad, especially in large companies, writing HTML a

Stand on its laurels, know the mountains outside the mountains, open Horizons, Fang knows behind.
Only by joining the catalyst of knowledge can the flame of life be lifted.

JavaScript has a bad reputation on the internet, but it's hard to find another language like it's so dynamic, so widely used, so rooted in our lives. Its low learning threshold makes many people call it a pre-school scripting language, and another thing that makes people laugh is the notion of a dynamic language that uses a high standard of static data types. In fact, you and JavaScript are in the wrong position, and now you're making JavaScript very angry. Here are five reasons why your JavaScr
