What is variable scope in TypeScript?

What is variable scope in TypeScript?

Variable scope in TypeScript refers to the accessibility of variables in different parts of your code. It determines where a variable can be accessed or modified.

Can you explain the difference between local and global scope?

Sure! Local scope refers to variables defined within a function or block, making them accessible only within that context. Global scope, on the other hand, allows variables to be accessed from anywhere in the code.

What about block scope? How does it work?

Block scope is introduced with let and const keywords in TypeScript. Variables declared within a block (like an if statement) are only accessible within that block.

Can you give an example of each type of scope?

Absolutely! For local scope, a variable declared inside a function is local. For global scope, a variable declared outside any function is global. For block scope, a variable declared with let inside an if block is only accessible within that block.
