What is API ,Explain me i am new in this
An API (Application Programming Interface) is basically a messenger that allows different software applications to talk to each other and exchange information, following a set of defined rules.
Think of it like this:
One piece of software wants something (data or a function) from another. The API is the go-between that takes the request and brings back the response, without them needing to know each other’s internal, complex details.
In short: It lets software work together.
