Can you explain the concept of lexical scoping?

Can you explain the concept of lexical scoping?

Sure! Lexical scoping is a way of defining how variable names are resolved in nested functions. It means that a function's scope is determined by its location within the source code.

How does it differ from dynamic scoping?

In dynamic scoping, a function's scope is determined by the call stack at runtime, while in lexical scoping, it's determined by the structure of the code at the time of writing.

Can you give me an example of lexical scoping?

Absolutely! Here's a simple example:

function outer() {
    let x = 10;
    function inner() {
        console.log(x);
    }
    inner();
}
outer(); // This will log 10

What are the advantages of using lexical scoping?

Lexical scoping makes code easier to understand and maintain, as it provides a clear structure for variable access and reduces the chances of variable name conflicts.
