There is now a <a href="https://marketplace.visualstudio.com/items/eg2.js-is-jsx" rel="nofollow">VS Code extension that allows <code>.js</code> files to be treated as <code>.jsx</code> files</a>.

Unfortunately the readme for the extension also warns:

<blockquote>
 when you install this extension you will loose all the existing language support provided for .js files
</blockquote>

Fortunately VS Code is now very close to <a href="http://blogs.msdn.com/b/user_ed/archive/2016/01/11/visual-studio-code-new-features-4-language-improvements-javascript-typescript-jsx-amp-tsx.aspx" rel="nofollow">adopting Salsa</a>, which means soon the js-is-jsx issue should be completely resolved.

blocks|key|1044181|text|我花了一段时间才弄明白这一点，但- JSX已经是Emmet的一部分--这是VS代码的一部分。我告诉Emmet还(另外)在常规JS文件中提供JSX片段。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1044182|只需将其放入您的设置文件：|1044183|"emmet.syntaxProfiles":+{

Took me a while to figure this out but – JSX is already part of Emmet – which is part of VS Code. I've told Emmet to also (additionally) make JSX snippets available in regular JS files.

Just put this in your settings file: 

<pre><code>"emmet.syntaxProfiles": {
 "javascript": "jsx"
} 
</code></pre>

blocks|key|1594559|text|虽然Dionys的答案有效，但是在Visual代码的最新版本中有更好的方法来实现这一点。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1594560|转到File>Prefrences>Settings，然后向下滚动并找到"Emmet“，打开选项卡，您将看到以下文本|offset|length|style|CODE|1594561|++//+Enable+Emmet+abbreviations+in+languages+that+are+not+supported+by+default.+Add+a+

Although Dionys' answer works there is a better way to do this in more recent versions of Visual Studio Code.

Go to <code>File&gt;Prefrences&gt;Settings</code> and then scroll down and find "Emmet" open the tab and you should see the following text

<pre><code> // Enable Emmet abbreviations in languages that are not supported by default. Add a 
 mapping here between the language and emmet supported language.
 // E.g.: {"vue-html": "html", "javascript": "javascriptreact"}
 "emmet.includeLanguages": {},
</code></pre>

So just follow the instructions and add <code>"emmet.includeLanguages": { "javascript": "javascriptreact" }</code> on the json at the right panel ( which will overwrite the user settings ).

Click on the bottom right on VS Code Editor where it says Javascript.

Visual Studio Code now <a href="https://code.visualstudio.com/Updates#_languages-jsx-colorization">supports JSX on 0.8 version</a>, but looks like the only way to activate it is with a <code>.jsx</code> file extension. It is not on the list to change the language mode manually, the nearest option is <code>JavaScriptReact</code>, but it doesn't parse the JSX tags.

I'm in a project with a lot of <code>.js</code> files with JSX and I can't change it.

Is there any other way to use JSX syntax without the <code>.jsx</code> extension?

Visual现在是，但是激活它的唯一方法是使用.jsx文件扩展名。它不在列表中手动更改语言模式，最近的选项是JavaScriptReact，但它不解析JSX标记。我在一个带有很多.js文件的项目中，我无法改变它。在没有.jsx扩展的情况下，还有其他方法来使用JSX语法吗？
