Description : Use the '|' operator to define a union type.
To create a union type in TypeScript, use the '|' operator between multiple types. For example, 'let id: string | number;' defines a variable 'id' that can be either a 'string' or a 'number'. This allows for more flexible type definitions and helps handle scenarios where a variable can have multiple types.

What is TypeScript?
TypeScript is a statically typed language that builds on JavaScript by adding optional types. It allows developers to catch errors at compile time rather than runtime, which can help improve code quality and readability. TypeScript code is transpiled to JavaScript, making it compatible with existing JavaScript codebases and environments.
