Can you explain type inference?
Sure! Type inference is a feature in some programming languages where the compiler automatically determines the type of a variable based on its value.
How does it work in languages like Python or JavaScript?
In Python, type inference happens at runtime, meaning the type is determined when the code is executed. In JavaScript, it uses dynamic typing, allowing variables to hold any type of value.
Are there any benefits to using type inference?
Yes, type inference can lead to cleaner code, reduce verbosity, and help prevent type-related errors during development.
Can you give me an example of type inference in action?
Certainly! In Python, if you write x = 10
, the interpreter infers that x
is an integer. If you later assign x = 'hello'
, it changes to a string.
