There are several ways to make money with Javascript:

You can offer web development services on platforms like Freelancer, Upwork, and Fiverr or even build your own portfolio website to showcase your skills.

2. Creating Javascript Libraries or Plugins: If you are an experienced Javascript developer, you can create your own libraries and plugins and sell them on marketplaces like CodeCanyon, NPM, or GitHub.

3. Teaching Javascript: If you are passionate about teaching, you can create courses or tutorials on platforms like Udemy, Skillshare, or Teachable and earn money by sharing your knowledge with others.

4. Offering Javascript Consulting Services: You can provide consulting services to businesses that need help with integrating Javascript into their website or creating custom solutions.

5. Building Web Applications: You can build your own web applications and monetize them through ads or subscriptions. Some popular examples of Javascript-based web applications are Trello, Slack, and Asana.

Here's an example of how to create a simple Javascript plugin to add custom animations to a website:

index.tsx
(function($) {
    $.fn.extend({
        customAnimate: function(options) {
            var settings = $.extend({
                speed: 800,
                easing: 'swing'
            }, options);
            return this.each(function() {
                var $this = $(this);
                $this.animate({
                    'opacity': 0,
                    'top': '-50px'
                }, settings.speed, settings.easing, function() {
                    $this.animate({
                        'opacity': 1,
                        'top': '0'
                    }, settings.speed, settings.easing);
                });
            });
        }
    });
}(jQuery));
