attached Type: Function Details: Called when vm.$el is attached to DOM by a directive or a VM instance method such as $appendTo(). Direct manipulation of vm.$el will not trigger this hook.

async Type: Boolean Default: true Usage: Vue.config.async = false When async mode is off, Vue will perform all DOM updates synchronously upon detecting data change. This may help with debugging in some scenarios, but could also cause degraded performance and affect the order in which watcher callbacks are called. async: false is not recommended in production.

array.$set(index, value) Arguments {Number} index {*} value Usage Set an element in the array to a value by index and trigger view updates. vm.animals.$set(0, { name: 'Aardvark' }) See also: Array Detection Caveats

array.$remove(reference) Arguments {Reference} reference Usage Remove an element from an array by reference and trigger view updates. This is a sugar method for first searching for the element in the array, and then if found, calling array.splice(index, 1). var aardvark = vm.animals[0] vm.animals.$remove(aardvark) See also: Mutation Methods
