If you're using Node / Webpack / Rollup / Browserify, etc, simply require the language module, then register it with Highlight.js.
var hljs = require('highlightjs');
var {pyret, scheme} = require('highlightjs-bootstrap');
hljs.registerLanguage("pyret", pyret);
hljs.registerLanguage("scheme", scheme);
hljs.highlightAll();
