You Don’t Need jQuery is a GitHub repository with a collection of code snippets that show how to do the most common jQuery bits in native JavaScript. The collection covers a whole range of subjects, like:

• Query selector
• CSS and style
• DOM manipulation
• AJAX
• Events
• Promises
• Animations
• … and more.

All examples should work just fine in all modern browsers.

Additionally, have a look at the You Might Not Need jQuery website.

Here’s something that came in helpful the other day at work – “Simple file upload using jQuery and AJAX“.  We were on the right track, but this blog post helped iron out the last few details.  In particular, this bit:

$.ajax({
        url: 'submit.php?files',
        type: 'POST',
        data: data,
        cache: false,
        dataType: 'json',
        processData: false, // Don't process the files
        contentType: false, // Set content type to false as jQuery will tell the server its a query string request
        success: function(data, textStatus, jqXHR)
        {
            if(typeof data.error === 'undefined')
            {
                // Success so call function to process the form
                submitForm(event, data);
            }
            else
            {
                // Handle errors here
                console.log('ERRORS: ' + data.error);
            }
        },
        error: function(jqXHR, textStatus, errorThrown)
        {
            // Handle errors here
            console.log('ERRORS: ' + textStatus);
            // STOP LOADING SPINNER
        }
    });

And a clarification of the parameters:

2 attributes need to be set to false:

• processData – Because jQuery will convert the files arrays into strings and the server can’t pick it up.
• contentType – Set this to false because jQuery defaults toapplication/x-www-form-urlencoded and doesn’t send the files. Also setting it to multipart/form-data doesn’t seem to work either.

There’s a GitHub repository with all the necessary example code.

A love letter to jQuery – very beautiful and sentimental …

So thank you jQuery! It’s been a wonderful 10 years. I hope we have another 10, but if we don’t it will always be with dignity and respect that I remember you and never less, because you do the perfect job of making yourself redundant. It is befitting that you do this so gracefully. If the time does come to say goodbye it will be because you have given us all that you can. To not be needed does not mean you will not forever be important to the me and the web.

Just a few weeks after we’ve started using jQuery 2, the news come in of the new major release of jQuery being not too far away:

It’s been a long time since we did a major release, and you certainly deserve one. So we’re glad to announce the first alpha of jQuery 3.0!

Despite the 3.0 version number, we anticipate that these releases shouldn’t be too much trouble when it comes to upgrading existing code. Yes, there are a few breaking changes that justified the major version bump, but we’re hopeful these breakages don’t actually affect that many people. The jQuery Migrate plugin can help you to identify compatibility issues in your code as well. Your feedback on the changes in this alpha will help us greatly, so please try it out on your existing code and plugins!

There are actually two releases here. First is jQuery 3.0, which supports modern browsers and environments from IE9 forward. Second is jQuery Compat 3.0, which includes support for IE8. As an added bonus, both jQuery and jQuery Compat will include support for Yandex.Browser, a freeware browser released in 2012. You can get the files from the jQuery CDN, or link to them directly
