// Your goal is to write a production-ready and maintainable JavaScript function. Apply code-golfing practices without sacrificing readability by putting everything on one line. Do not include any comments in your code.
//
// Write an async JavaScript function 'calculateDeterminant' that calculates the determinant of a square matrix.
// - The function must accept an n x n matrix, represented as an array of arrays.
// - You MUST use a dynamic import() to load the 'mathjs' library from a CDN.
// - You MUST use the library's built-in 'det' function to perform the calculation.
// - The function should return the determinant value.
