Computed getters #

Computed getters are functions that are used like properties in your component. They are defined with the computed property.

They are memoized functions which means the result of the getter is cached for subsequent executions. This is useful when creating projections from large sets of data.

Setting local state will automatically reset the computed cache.

You can access getters with this in your component render function.

computed: {
myGetter () {
const name = 'Andy'
return `Hello, I'm ${name}`
}
},
render () {
return html`<div>${this.get.myGetter}</div>`
}
