NG8002Angular

Angular: NG8002: Can't bind to 'ngModel' since it isn't a known property of 'input'

[Vue warn]: Duplicate keys found during updateVue

Vue: [Vue warn]: Duplicate keys found during update: "5", possible duplicate or missing keys

Items in a `v-for` list share the same `:key`, which breaks Vue's diffing.

v-model cannot be used on a prop (compile error)Vue

Vue: [@vue/compiler-sfc] v-model cannot be used on a prop, because local prop bindings are not writable

A template uses `v-model` on a prop (or a `v-for` alias), which can't be assigned.

ESLint's Vue rules require component names with at least two words to avoid clashing with HTML elements.

Cannot find module './App.vue' or its corresponding type declarationsVue

Attributes (class, style, listeners) passed to a component can't be applied because the component has multiple root nodes.

react-hooks/exhaustive-depsReact

React Hook useEffect has a missing dependency (react-hooks/exhaustive-deps)

ESLint warns that the effect reads a value that isn’t in its dependency array, so it may use a stale value.
