How to assign the correct typing to React.cloneElement when giving properties to children? : <p>I am using React and Typescript. I have a react component that acts as a wrapper, and I wish to copy its properties to its children. I am following React's guide to using clone element: <a href="https://facebook.github.io/react/blog/2015/03/03/react-v0.13-rc2.html#react.cloneelement" rel="noreferrer">https://facebook.github.io/react/blog/2015/03/03/react-v0.13-rc2.html#react.cloneelement</a>. But when using using <code>React.cloneElement</code> I get the following error from Typescript:</p>

<pre><code>Argument of type 'ReactChild' is not assignable to parameter of type 'ReactElement&lt;any&gt;'.at line 27 col 39
  Type 'string' is not assignable to type 'ReactElement&lt;any&gt;'.
</code></pre>

<p><strong>How can I assign the correct typing's to react.cloneElement?</strong></p>

<p>Here is an example that replicates the error above:</p>

<pre><code>import * as React from 'react';

interface AnimationProperties {
    width: number;
    height: number;
}

/**
 * the svg html element which serves as a wrapper for the entire animation
 */
export class Animation extends React.Component&lt;AnimationProperties, undefined&gt;{

    /**
     * render all children with properties from parent
     *
     * @return {React.ReactNode} react children
     */
    renderChildren(): React.ReactNode {
        return React.Children.map(this.props.children, (child) =&gt; {
            return React.cloneElement(child, { // &lt;-- line that is causing error
                width: this.props.width,
                height: this.props.height
            });
        });
    }

    /**
     * render method for react component
     */
    render() {
        return React.createElement('svg', {
            width: this.props.width,
            height: this.props.height
        }, this.renderChildren());
    }
}
</code></pre>
