Web Components & Shadow DOM

What is the purpose of the <slot> element in Web Components?

class MyCard extends HTMLElement {
  constructor() {
    super();
    this.attachShadow({ mode: 'open' });
    this.shadowRoot.innerHTML = `
      <div class="card">
        <h2><slot name="title"></slot></h2>
        <div><slot></slot></div>
      </div>
    `;
  }
}

To create event listeners
To define component properties
To allow content projection from the light DOM
The <slot> element serves as a placeholder for content projection in Web Components. It: 1) Allows content from the light DOM (regular DOM) to be displayed within the Shadow DOM, 2) Can be named to allow multiple distinct content projections, 3) Provides a way to create component templates with placeholder content, 4) Enables composition and reusability in Web Components.
