Group array of objects by object value

I have files stored as an array of objects, each file has a directory. What I need is to have directories stored as an array of objects each containing an array of their files.

How would I process my array to get from this:

[    {      local: 'comp_0.mp4',      directory: 'video_4',      remote: 'http://b6fo00nKJM.mp4',    },    {      local: 'comp_1.mp4',      directory: 'video_4',      remote: 'http://J-CgEY_zcL.mp4',    },    {      local: 'comp_0.mp4',      directory: 'video_5',      remote: 'http://GHH66-a7eY.mp4',    },    {      local: 'comp_1.mp4',      directory: 'video_5',      remote: 'http://ZF0eqIEf5g.mp4',    },  ];  

To this...

[    {      directory: 'video_4',      files: [        {          local: 'comp_0.mp4',          remote:'http://b6fo00nKJM.mp4',        },        {          local: 'comp_1.mp4',          remote:'http://J-CgEY_zcL.mp4',        },      ],    },    {      directory: 'video_5',      files: [        {          local: 'comp_0.mp4',          remote:'http://GHH66-a7eY.mp4',        },        {          local: 'comp_1.mp4',          remote:'http://ZF0eqIEf5g.mp4',        },      ],    },  ];
