What are some examples of TypeScript annotations?
An example of an AI chatbot conversation about TypeScript annotations and their usage.
Can you give me some examples of TypeScript annotations?
Sure! TypeScript annotations are used to specify the types of variables, function parameters, and return values. For example, you can annotate a variable like this: let age: number = 30;.
What about function annotations?
For functions, you can annotate the parameters and return type. For instance: function greet(name: string): string { return 'Hello, ' + name; }.
Are there any annotations for arrays?
Yes! You can annotate arrays using the syntax: let numbers: number[] = [1, 2, 3]; or let names: Array<string> = ['Alice', 'Bob'];.
Can you explain the 'any' type?
The 'any' type allows you to opt-out of type checking. For example: let data: any = 42; data = 'Now I am a string';.
