React UI Component which like a love letter

import * as React from 'react';
export var isValidElement = React.isValidElement;
export function replaceElement(element, replacement, props) {
    /** 传入的element不是ReactNode的时候，返回replacement */
    if (!isValidElement(element))
        return replacement;
    return React.cloneElement(element, typeof props === 'function' ? props(element.props || {}) : props);
}
