Well, "t" is either "min" or "max". And edges is an array of 2 element arrays, e.g.
edge=[["AB",3], ["BC",9], ["AC",5]]
sort takes a function of two parameters that returns a number indicating whether the first parameter is smaller or bigger than the second parameter. The parameters are elements of the array. In our case these are 2 element arrays. In the code example, these are destructured as edge_a (e.g. "AB") and a (e.g. 3) respectively edge_b and b. The array edges is being sorted by the second element of the 2 element arrays.
Hope this helps.
Ah OK. I didn't understand that t was a variable previously set to "min" or "max". Maybe it would be clearer to precise it, o add a line of code to show it.

I deleted the const because it doesn't contribute to the point I want to make. It's much clearer now. Thanks for your comment.
