Thanks for putting it together. Use JSLint and minification (JSMin, for example) before going live. Great reference for when you need something quick. You wrote you didnt want explanations. HTML5 is the thing to talk about these days.
Thanks Konrad for this good review, As I said the list is open to the readers suggestions and improvments, I’ll check this list and others, after that update the article ;). Great “little” compilation of tips & tricks. myArray.length = 0; // myArray will be equal to []. Use them on the source of your pages, in html part.
23 – Use the map() function method to loop through an array’s items. And I just saw some of my bullets below have been commented on while I wrote. http://jsperf.com/push-vs-length-test/28, So it depend on some case, and primitive operations not aways faster, (See: http://www.avronp.com/nsn/nsn_stringvb/rsrcs/js/foundations/js_string.js) }.
The developers who master JavaScript and write organized and performant code have become the most sought after in the job market. Hopefully I can work out the rest for myself if I need to. They are good practice in limited use at the beginning of methods to set local variables and such.
As the JavaScript app scene has grown and proven that it is viable, there has been a great effort from the JavaScript community to share code to accomplish some awesome things and speed up development time. You can refer to the images for inputs and outputs. See this video for proof if you do not believe me. The delete method should be used to delete an object property. Bugfixes/Improvements: Here are some examples for those of you that have no idea what I mean: Even simple animations can add a lot to a website; they keep you engaged and make you want to just keep on going to see what more it has to give.
// .lowerhtml | Lowerhtml() | Convert HTML tags to lowercase );
28 – Cache variables that need calculation or querying. It shoud be:
Web Assembly and JavaScript together now offer the best of native development and website development, allowing companies to build applications and games that make use of your computerâs native hardware whilst running through a web browser. foreach ($prevPost as $post) {
Histography. Also a good read on flippinawesome: http://flippinawesome.org/2013/11/25/fun-with-javascript-native-array-functions/.
Make your website wonderful with free Script codes.
New features can also be developed into apps as companies are not having to split resources across two different operating systems. Avoid using it when you have more than 10 cases.
You could abort the connection if an XHR takes a long time (for example, due to a network issue), by using setTimeout() with the XHR call.
// .count | Count() | counts occurrences of a pattern in a string In this article I have used my own code snippets. Many JavaScript events have popped up around the world, which draw together developers from all different backgrounds to learn about upcoming trends in the language. If people only did that, they could be as sloppy as they liked with semicolons. I like your blog article.
var n = 2.414233; You can refer to the input and output images attached. var x = 2; But it depends entirely of your scope structure or your browser or your real array end. Here we pick some of our favourite examples of JavaScript in action for your inspiration.
I know that there are many other tips, tricks and best practices, so if you have any ones to add or if you have any feedback or corrections to the ones that I have shared, please adda comment. 36 Try using an action object, instead.
“hello world”
Some of them good ones. – #7 `})(10,20)` – missing semicolon (see point #4) #3 I would add an exemple. Seriously… Firefox (and other browsers) tend to ignore trailing commas – which in this case incorrectly chops off an “undefined” array value. – #27 interesting, but not useful So if you were to add another number to n after the toFixed, it would simply add it to the end as in string concatenation.
Some would prefer stacking objects anyway.
But how about this one: for(var i=myArray.length; i–;){
#43 is missing the colon in your conditional operator. He has created applications using ASP.NET and C#, but now he’s more interested to JavaScript, HTML5, SSJS, Cloud, and mobile. And this list provides just that.
