 * @example
 * import { esc } from 'deleight/apriori'
 * const obj = { a: 1, b: 'no special chars', c: '<p>But I am a paragraph</p>', d: { e: '<p>"esc" will still work here</p>' } }
 * const escObj = esc(obj);
 * console.log(escObj.c);     // &lt;p&gt;But I am a paragraph&lt;/p&gt;
 * console.log(escObj.d.e);     // &lt;p&gt;&quot;esc&quot; will still work here&lt;/p&gt;
