How to check typing speed with javascript code

To type 100 words in 1 minute with JavaScript code, you can use a simple formula based on the number of words, start time and end time. The formula is wpm = nbrOfWords / ( (endTime - startTime) / 60000).²¹

Here's an example of how you can display typing speed using JavaScript code:

```javascript

var lastrun = new Date ();

textarea.onkeyup = function () {

  var words = textarea.value.split (' ');

  var minutes_since_last_check = somefunctiontogetminutesdifference (new Date (), lastrun);

  var wpm = (words.length-1)/minutes_since_last_check;

  //show the wpm in a div or something

};

```
