code: function wrapChildren(children) {
    let shouldWrap = Children.count(children) > 1
    if (!shouldWrap)
      Children.forEach(children, child => {
        shouldWrap = typeof child === 'string'
      })
    if (shouldWrap) return <span>{children}</span>
    return children
  }
docs: Если нужно оборачиваем children в <span>
  @param  {ReactElement} children
  @return {ReactElement}
