The following code can be used instead

```ts | pre const a = 1; ```

marked.use({
  renderer: {
    code(code, infostring: string, escaped) {
      const [lang, ...attrsString] = infostring.split(' | ')
      console.log('lang', lang) // ts
      console.log(attrsString) // [ 'pre' ]
      const language = hljs.getLanguage(lang) ? lang : 'plaintext'
      return `<pre><code class="hljs language-${lang}">${
        hljs.highlight(code, { language }).value
      }</code></pre>`
    }
  }
})
