Too Long; Didn't Read
Vue is like any other tool we use on the web - your mileage will vary depending on how you use it. If you write poorly optimized code, you'll still get a slow website. Today we'll be looking at how we can optimise performance using two little-known Vue HTML attributes known as `v-once` and v-memo. Both of these allow us to optimize when a component or component tree is re-rendered. V-once can be used pretty much anywhere - including within `for` loops - making it universally useful in Vue.
