How to add custom JavaScript via Microthemer

To summarise the above video:

• Go to View > Code editor > JS to enter JavaScript code
• The code you enter will be added to an external JavaScript file: wp-content/micro-themes/active-scripts.js
• Do not enter script tags, as these are not necessary when adding code to a JavaScript file
• You can use jQuery by adding the document.ready function.
• You can load native WordPress JS libraries via General > JS libraries
• Use Ctrl + S to save your JavaScript and reload the page
• Microthemer will report any JS errors at the top right of the screen
