How do I extract code from markdown code block string?

Question

If I have this string like this

```
console.log()
```
Hello

or

Hello
```
console.log()
```

or

```console.log()``` Hello

or

Hello ```console.log()```

How do I get just the console.log() string?

---------------------------------------------- Edit ----------------------------------------------

The regex I use is the combination between regex answered by @Himanshu Tanwar with the one suggested by @ASDFGerte

var code = s.match(/```([^`]*)```/)[1]

the easiset is to render to a fragment, then use the dom/css selectors to hit it. — dandavis

You can try doing it with regular expression

var s = "```console.log()```Hello";

var code = s.match(/```(.*)```/)[1]

Remember to .trim() the result :)

preferrably use ([^`]*) or you will get unwanted results if the string includes several code blocks.

@ASDFGerte You mean that the regex is like this, /```([^`]*)```/?

Yes. Try both with "```console.log()```Hello```console.log()```Hello".match( and you will see the difference.

/```[^`]*```/gmi
