Inline rendering with document​.currentScript Lean Rada describes a neat trick that takes advantage of the document.currentScript property. You can use that to drop in a tiny inline element that replaces itself when the page loads: The year is document.currentScript.replaceWith( new Date().getFullYear()) If you define a shortcut function like this: $=(...n)=>document.currentScript.replaceWith(...n) You get a tiny template language: The year is $(new Date().getFullYear()) Tags: javascript
