What are the different types of errors in TypeScript?

In TypeScript, errors can be categorized into three main types: compile-time errors, runtime errors, and logical errors.

Can you explain compile-time errors with an example?

Sure! Compile-time errors occur when TypeScript detects issues during the compilation process, like type mismatches. For example:

let num: number = 'string'; // This will cause a compile-time error

What about runtime errors?

Runtime errors happen when the code is executed. For instance, trying to access a property of undefined will throw an error at runtime:

let obj: any;
console.log(obj.property); // This will cause a runtime error

And what are logical errors?

Logical errors occur when the code runs without crashing, but produces incorrect results. For example:

function add(a: number, b: number): number {
    return a - b; // This is a logical error; it should be addition
}
