Code Explanation

Let's break down the function line by line to understand its operations and syntax.

    Function Declaration:

    language-javascript

function generateAdvancedGlitchedEmail(baseEmail, layers, glitchTypes, intensities) {

This line defines a function named generateAdvancedGlitchedEmail that takes four parameters:

    baseEmail: The original email address to be glitched.
    layers: The number of times the email should be encoded.
    glitchTypes: An array of glitch types to apply.
    intensities: An array of probabilities corresponding to each glitch type.

Variable Initialization:

language-javascript

let glitchedEmail = '';

Here, we initialize an empty string glitchedEmail that will hold the final glitched email.

Iterating Over Each Character:

language-javascript

for (let char of baseEmail) {

This for...of loop iterates over each character in the baseEmail. Each character is processed individually.

Glitch Application Flag:

language-javascript

let applyGlitch = false;

A boolean flag applyGlitch is initialized to false. It will be set to true if any glitch is applied to the current character.

Applying Glitches:

language-javascript

glitchTypes.forEach((type, index) => {

The forEach method iterates over the glitchTypes array. For each type, it checks if a glitch should be applied based on the corresponding intensity.

Random Glitch Decision:

language-javascript

if (Math.random() < intensities[index]) {

This line generates a random number between 0 and 1. If this number is less than the intensity for the current glitch type, the glitch will be applied.

Switch Statement for Glitch Types:

language-javascript

switch (type) {

A switch statement is used to determine which type of glitch to apply based on the type variable.

    Line Noise:

    language-javascript

case 'line-noise':
    glitchedEmail += '%' + Math.floor(Math.random() * 256).toString(16).toUpperCase();
    break;

If the glitch type is 'line-noise', a random hexadecimal character (representing noise) is appended to glitchedEmail.

Digital Glitch:

language-javascript

case 'digital':
    glitchedEmail += char + Math.floor(Math.random() * 10);
    break;

For 'digital', the original character is followed by a random digit (0-9).

Runaway Code:

language-javascript

case 'runaway-code':
    glitchedEmail += char + (Math.random() < 0.5 ? '!' : '#');
    break;

In the 'runaway-code' case, the character is followed by either '!' or '#' based on a random decision.

Default Case:

language-javascript

    default:
        glitchedEmail += char;

    If none of the glitch types match, the original character is added without any changes.

No Glitch Applied:

language-javascript

if (!applyGlitch) {
    glitchedEmail += char;
}

If no glitch was applied during the iteration, the original character is appended to glitchedEmail.

Encoding the Glitched Email:

language-javascript

for (let j = 0; j < layers; j++) {
    glitchedEmail = encodeEmail(glitchedEmail, document.getElementById('encodingType').value);
}

This loop encodes the glitchedEmail multiple times based on the layers parameter. The encoding type is fetched from an HTML element with the ID encodingType.

Return Statement:

language-javascript

return glitchedEmail;
}

Finally, the function returns the fully processed glitchedEmail.
