What aspects do developers pay more attention to in JavaScript?

In a technical community or forum, a certain technology or opinion may cause widespread discussion or even quarrel among users. However, some technical posts are relatively calm.

James Padolsey observed some JavaScript communities and summed up what aspects of JavaScript developers are more concerned about, or which technologies are more likely to cause heated discussions among developers.

The following is a topic that is easily discussed by developers:

1. Insert a semicolon automatically

2. eval is annoying.

3. ECMAScript 5 shimsshims mainly aims to solve the style problem of HTML5 elements in old IE)

4. browser support

5. JSLint and JSHint

6. JavaScript vs. CoffeeScript

7. JavaScript vs. Dart

8. Features of ECMAScript 5/6, such as "=> ")

9. coding conventions: white-space and braces)

10. MVC frameworks such as Backbone, AngularJS, Knockout, and Ember)

11. Node. js

12. performance difference in milliseconds

13. jQuery vs. Dojo vs. YUI vs. Prototype vs. Mootools vs. ExtJS

14. Native prototype Enhancement

In the community, there are many very valuable discussions on the above topics, but there are often a lot of arguments that do not have a factual basis, but only maintain their own points of view.

Developers will also be concerned about the following topics, but there will be no heated discussions similar to the above topics:

1. Compression Tool

2. JavaScript Engine

3. Build tools

4. Web checker/Analyzer

5. API naming rules

6. AMDAsynchronous Module Definition, asynchronous Module Definition)
