bind:this in Svelte allows you to get a reference to a DOM element or a component instance. This is useful when you want to directly manipulate the element or call methods on a component from your script.
Here, inputEl becomes a reference to the <input> element, allowing the focusInput function to call inputEl.focus() directly.
Here, childRef refers to the Child component instance, allowing you to call methods or access properties defined inside the component.
Use bind:this to get references to DOM elements or component instances.
Useful for imperative actions like focusing inputs, scrolling, or calling methods.
Avoid overusing it; prefer reactive and declarative patterns when possible.
When used on components, you can only access public methods and properties.
