+# eagerComputed
+
+Eager computed without lazy evaluation.
+
+Learn more at [Vue: When a computed property can be the wrong tool](https://dev.to/linusborg/vue-when-a-computed-property-can-be-the-wrong-tool-195j).
+
+- Use `computed()` when you have a complex calculation going on, which can actually profit from caching and lazy evaluation and should only be (re-)calculated if really necessary.
+- Use `eagerComputed()` when you have a simple operation, with a rarely changing return value – often a boolean.
+
+## Usage
+
+```js
+import { eagerComputed } from '@vueuse/core'
+
+const todos = ref([])
+const hasOpenTodos = eagerComputed(() => !!todos.length)
+
+console.log(hasOpenTodos.value) // 0
+toTodos.value.push({ title: 'Learn Vue' })
+console.log(hasOpenTodos.value) // 1
+```
