What are the benefits of using pure functions in programming?
Pure functions are functions that always produce the same output for the same input and have no side effects. This leads to easier testing and debugging.
Can you explain what you mean by 'no side effects'?
Sure! No side effects means that a pure function does not alter any external state or variables. It only relies on its input parameters.
How do pure functions help with testing?
Since pure functions always return the same result for the same inputs, they can be tested in isolation without worrying about external factors.
Are there any downsides to using pure functions?
One downside is that pure functions can sometimes lead to more complex code when dealing with stateful operations, but the benefits often outweigh this.
