+# reactiveOmit
+
+Reactively omit fields from a reactive object.
+
+## Usage
+
+### Basic Usage
+
+```ts
+import { reactiveOmit } from '@vueuse/core'
+
+const obj = reactive({
+  x: 0,
+  y: 0,
+  elementX: 0,
+  elementY: 0,
+})
+
+const picked = reactiveOmit(obj, 'x', 'elementX') // { y: number, elementY: number }
+```
+
+### Predicate Usage
+
+```ts
+import { reactiveOmit } from '@vueuse/core'
+
+const obj = reactive({
+  bar: 'bar',
+  baz: 'should be omit',
+  foo: 'foo2',
+  qux: true,
+})
+
+const picked = reactiveOmit(obj, (value, key) => key === 'baz' || value === true)
+// { bar: string, foo: string }
+```
+
+### Scenarios
+
+#### Selectively passing props to child
+
+```vue
+<script setup lang="ts">
+import { reactiveOmit } from '@vueuse/core'
+
+const props = defineProps<{
+  value: string
+  color?: string
+  font?: string
+}>()
+
+const childProps = reactiveOmit(props, 'value')
+</script>
+
+<template>
+  <div>
+    <!-- only passes "color" and "font" props to child -->
+    <ChildComp v-bind="childProps" />
+  </div>
+</template>
+```
+
+## Type Declarations
+
+```ts
+export type ReactiveOmitReturn<
+  T extends object,
+  K extends keyof T | undefined = undefined,
+> = [K] extends [undefined] ? Partial<T> : Omit<T, Extract<K, keyof T>>
+export type ReactiveOmitPredicate<T> = (
+  value: T[keyof T],
+  key: keyof T,
+) => boolean
+export declare function reactiveOmit<T extends object, K extends keyof T>(
+  obj: T,
+  ...keys: (K | K[])[]
+): ReactiveOmitReturn<T, K>
+export declare function reactiveOmit<T extends object>(
+  obj: T,
+  predicate: ReactiveOmitPredicate<T>,
+): ReactiveOmitReturn<T>
+```
