Have you ever used the 'any' type in TypeScript? What can replace it?

The 'any' type in TypeScript is used to denote a value of any type, effectively disabling type checking for that variable. It can be replaced with safer alternatives, such as:

• Using the 'unknown' type, which requires explicit type assertion before use, thereby increasing safety.
• Defining specific types or union types to restrict possible values.

Example of replacing 'any' with 'unknown':

let value: unknown = getValue();

if (typeof value === 'string') {
  console.log(value.toUpperCase());
}

Thus, 'unknown' helps avoid errors related to incorrect use of a value, unlike 'any'.
