Understanding the weird syntax with curly braces in a constructor initializer list

Question

So I was just browsing the source code of a library when I encountered this.

Font::Font(const sf::Font& font) :
        m_font{std::make_shared

        

Answer 1

The class Font has a member called m_font of type std::shared_ptr, so in the constructor of the class Font that member is being initialized with a shared pointer to font.
