Great post. Functions should always be so small they can be easily tested and read!

Testing code becomes really easy when functions(even classes) just do one thing.

Reading code becomes extremely easy to read when functions just do one thing.

Another way to answer the question

how we can know when our function is not doing just one thing?

Is by telling what the function does. As soon as we describe and use the word "AND" that function is doing more than it should.

"my function sends info to third-party and updates the record" red flag.
