This project is about creating an ASCII animation in a web page. The animation cycles through a series of ASCII characters to create a dynamic visual effect.
The main part of the code is a function called updateFrame that updates the text content of each span element in the textDiv with a calculated ASCII character. This function is called repeatedly using requestAnimationFrame to create a smooth animation effect.
The ASCII character for each span is calculated by the main function, which takes the index of the span and the current frame of the animation as arguments. The function calculates an index in the asciiChars array based on the index and frame, and returns the ASCII character at the calculated index.
The asciiChars array is defined as a string of ASCII characters split into an array of individual characters. The spans NodeList is a collection of all the span elements in the textDiv.
The updateFrame function also includes a condition to change the text back to the original text when the frame is divisible by 100. This is done by keeping track of the original text of each span in the originalText array.
If the length of textDiv's textContent is greater than 10000, a random span's textContent is changed to an ASCII character. This is to prevent the text from becoming too long.
To run the animation, simply open the HTML file in a web browser. The animation will start automatically.
