Simple Javascript rendering with template strings

For tiny projects, template strings can make simple things really easy, even without using libraries.

const template = (title, items) => `
  <h2>${title}</h2>

  ${subtitle ? `<h3>${subtitle}</h3>` : ''}

  <ul>
    ${items.map(item => `
      <li>${item}</li>
    `).join('')}
  </ul>
`;

Some aspects of this may seem familiar if you’ve been using React. Replacing traditional template language loop constructs with .map takes getting used to, but the realization that you don’t need any new language constructs is itself quite cool.

When combined with querySelector, addEventListener and fetch, the thought of doing small projects without large scale library support (beyond an ES6 transpiler) becomes quite reasonable.
