What is type inference in TypeScript?
An example of an AI chatbot conversation about understanding type inference in TypeScript.
What is type inference in TypeScript?
Type inference in TypeScript is the ability of the compiler to automatically deduce the type of a variable based on its value.
Can you give me an example of type inference?
Sure! If you declare a variable like let num = 5;, TypeScript infers that num is of type number.
What happens if I try to assign a different type to it?
If you try to assign a different type, like num = 'hello';, TypeScript will throw an error because it expects a number.
How can I override type inference?
You can override type inference by explicitly declaring the type, like let num: string = 'hello';.
