Two-dimensional Gaussian function in JavaScript

gaussian.js

/**

 * @param {number} y0

 * @param {number} sigmaY
 * @returns {Function}
 */
function makeGaussian(amplitude, x0, y0, sigmaX, sigmaY) {
    return function(amplitude, x0, y0, sigmaX, sigmaY, x, y) {
        var exponent = -(
                ( Math.pow(x - x0, 2) / (2 * Math.pow(sigmaX, 2)))
                + ( Math.pow(y - y0, 2) / (2 * Math.pow(sigmaY, 2)))
            );
        return amplitude * Math.pow(Math.E, exponent);

}

// USAGE
var gaussian = makeGaussian(300, 200, 200, 50, 50);

console.log(gaussian(100,100)); // ~5
console.log(gaussian(200, 200)); // 300

I love it! I'm using it an a modular kernel filter system to implement gaussian blur.
Here's my contribution for better intellisense:
