Render functions
Rather than supplying a string template for your component, you can instead
supply a render function. Without understanding the syntax, you can probably tell
from the following example that the render function is generating a semantically
equivalent template to the string template in the previous example. Both define a
div with an id attribute of my-component and with inner text of My component:
Vue.component('my-component', { render(createElement) {
createElement('div', {attrs:{id:'my-component'}}, 'My component'); //
Equivalent to My component } })
Render functions are more efficient because they don't require Vue to first
compile the template string. The downside, though, is that writing a render
function is not as easy or expressive as markup syntax, and, once you get a large
template, will be difficult to work with.
