what are first class functions and first order functions..? Both are same or not..? Is there any similarities/difference between first order and first class functions in javascript.
I tried to get an answer but didn't get a well-explained one. please help me.. Many sites only explain what is first-class function, not first-order functions. If both are the same, they don't mention it.
In JavaScript, a first-order function is a function that is not a higher-order function.
A higher-order function is a function that takes one or more functions as arguments, or returns a function as its result.
First-class functions are functions that can be used like any other value, such as being assigned to a variable, passed as an argument to a function or returned as a result from a function.
In JavaScript, all functions are first-class functions, so a first-order function is also a first-class function.
