JavaScript: Countable.js

This article is about a very small, rather unknown,  but a very powerful JavaScript library which will make your life easy without making your web app unnecessarily heavy. Well, this may be useful in a use case, where you need to show count of words, characters,  sentences etc to the end-user which he enters into a text field or to store it in a database for some data analyzing kind of thing. So let's start with some code: <input type="text" id='usertext'></textarea> <script>   Countable.count(document.getElementById('usertext'), counter =>     console.log(counter)   ) </script> Now you should see: {paragraphs: 0, sentences: 0, words: 0, characters: 0, all: 0} With the Countable.count function we get the current state of our text field.  But if we change anything in it now, the function will not be called again.

Javascript: Mousetrap.js

Mousetrap is a small standalone library with no external dependency. It is used for handling keyboard events, shortcuts in the browser. Mostly when building complex UI's, it is helpful or necessary to provide the user with keyboards shortcuts. This is also conceivable in video games or something like that. Let's look at the example: Bind a single Key: Mousetrap.bind(‘4’, function() {   console.log(‘you pressed 4’) }) Note: It makes a difference whether it is a capital or small letter that was defined or pressed. For Mousetrap, for example, x is not equal to X. Bind a single key, trigger the function when you let the key come up, after holding it down. Mousetrap.bind(‘x’, function() {   console.log(‘You pressed x and let it come up’) },‘keyup’) Trigger when the a, b & c keys are pressed in sequence. The specified sequence must be observed. Mousetrap.bind(‘a b c’, function() {   console.log(‘You pressed a, then b & after that you pressed c’) }
