Key Differences between First-Order Function and Higher-Order Function
First-Order Function | Higher-Order Function |
---|---|
Function is treated as a variable that can be assigned to any other variable or passed as an argument. | The function receives another function as an argument or returns First-order a new function or both. |
The “first-class” concept only has to do with functions in programming languages. | The “higher-order” concept can be applied to functions in general, like functions in the mathematical sense. |
The presence of the First-class function implies the presence of a higher-order function. | The presence of a Higher-order function does not imply the presence of a First-order function. |
