tiny-entitize-deentitize.js

const [ entitize, deentitize ] = (charmap => [
    h => charmap.reduce((v, [char, entity]) => v.replaceAll(char, entity), h),
    h => charmap.reduce((v, [char, entity]) => v.replaceAll(entity, char), h),
])([['&','&amp;'],['<','&lt;'],['>','&gt;'],['"','&quot;'],["'",'&#039;']]);

// minified
const [e,d]=(m=>[h=>m.reduce((v,[c,e])=>v.replaceAll(c,e),h),h=>m.reduce((v,[c,e])=>v.replaceAll(e,c),h)])([['&','&amp;'],['<','&lt;'],['>','&gt;'],['"','&quot;'],["'",'&#039;']]);

// example
var html = '<b>You & I really just "<i>get it</i>", don\'t we?</b>';
var entitized = '&lt;b&gt;You &amp; I really just &quot;&lt;i&gt;get it&lt;/i&gt;&quot;, don&#039;t we?&lt;/b&gt;';
console.log(entitize(html) === entitized, entitize(html));
console.log(deentitize(entitized) === html, deentitize(entitized));
