What is dead code and can you give me some examples?

Dead code refers to parts of the code that are never executed or used. For example, a function that is defined but never called is considered dead code.

Can you show me a specific example in JavaScript?

Sure! Here's an example:

function unusedFunction() {
    console.log('This function is never called.');
}

In this case, unusedFunction is dead code if it's not invoked anywhere in the program.

What are the potential issues with having dead code in a project?

Dead code can lead to increased maintenance costs, confusion for developers, and can make the codebase harder to read and understand.
