#FizzBuzz in 44

u/SockTaters

This is a little refactored, but u/DaSpider's solution also works in 44 characters with just the t|=0 trick. A slicing solution is also very close at 45 char: t|=0;throw'FizzBuzz'.slice(t%3&&4,t%5?4:8)||t

Amazing!

The code you have provided is a JavaScript program that uses the u() function to draw an animation on an HTML canvas element. The u() function is called 60 times per second, and uses the elapsed time t as a parameter to create the animation. The code uses a number of shorthand functions and variables to simplify the implementation of the u() function. The S, C, and T variables are shorthand for the Math.sin(), Math.cos(), and Math.tan() functions, respectively. The R() function is used to generate rgba color strings, and the c and x variables represent the canvas element and its 2D context, respectively. The u() function uses a loop to iterate over a range of values for i, and uses these values to calculate the X, Y, and Z coordinates for each iteration. The X and Y coordinates are used to draw a rectangle on the canvas using the fillRect() method, and the Z coordinate is used to scale the rectangle and create the illusion of depth. The globalAlpha property is used to set the transparency of the rectangles, and the style.filter property is used to invert the colors of the canvas. Overall, this code appears to be a simple example of how the canvas element and the u() function can be used to create an animation in JavaScript. It uses some advanced features of the language, such as shorthand functions and the canvas element, to create a visually interesting effect.

Note: Just "sepia(" works as a 100% sepia filter. No need for a percentage or to even a closing parenthesis.
