What is the React pattern where the children prop accepts a function?
问题
The React pattern where a component's children prop accepts a function, allowing a component to pass data to arbitrary children, doesn't have a specific widely-recognized name. It's often referred to as "render prop pattern" or "function as children pattern" informally.
As for whether it's a good practice or an anti-pattern, it depends on the use case. This pattern can be quite powerful and flexible for certain scenarios, allowing dynamic rendering and data passing to child components. However, overusing it unnecessarily can make the code less readable. So, it's essential to evaluate its appropriateness on a case-by-case basis.

I am trying to find the name of the React pattern where a component's children prop accepts a function, allowing a component to pass data to arbitrary children.
Here's an example of this pattern from Formik's docs:
<Formik>
{({ handleSubmit, handleChange, handleBlur, values, errors }) => (
<form onSubmit={handleSubmit}>
<input
type="text"
onChange={handleChange}
onBlur={handleBlur}
value={values.name}
name="name"
/>
{errors.name &&
<div>
{errors.name}
</div>}
<button type="submit">Submit</button>
</form>
)}
</Formik>
I tried searching for descriptions of this pattern, but was not able to find anything.
Does this pattern have a name? Are there good uses for it? Is it an anti-pattern?
