Property ‘children’ does not exist on type ‘reactnode’

by

This error occurs in React when the property ‘children’ is used on a variable or object of type ‘reactnode’ that does not have the ‘children’ property defined.

In React, the ‘children’ property is a special property used to render the child elements or components that are passed to a component. It allows components to have nested content.

To fix this error, ensure that you are using the ‘children’ property only on components or elements that actually have child elements.

Example 1:


function MyComponent(props) {"{"}

  return // Some JSX content

{"}"}

const element = ;

{/* This will throw the error because MyComponent does not have 'children' property */}
console.log(element.props.children);

In this example, the MyComponent does not define the ‘children’ property, so trying to access it will result in the “property ‘children’ does not exist on type ‘reactnode'” error.

Example 2:


function ParentComponent(props) {"{"}

  return

{props.children}

;

{"}"}

const element = (

  

    

Hello, World!

  

);

{/* This will log the h1 element */}
console.log(element.props.children);

In this example, the ParentComponent defines the ‘children’ property and renders it using the {props.children} syntax. When accessing the ‘children’ property on the element, it will return the h1 element because it is passed as a child to the ParentComponent.
