Function names should say what they do

☑️ Topic: Functions

☑️ Idea: Say what the function does with its name. The name should tell you what it expects as inputs as well.

☑️ Benefits: Readability

☑️ Guideline: You should know what a function does by reading its name.


// BAD
function addToDate(date, month) {
  // ...
}
const date = new Date();
// It's hard to tell from the function name what is added
addToDate(date, 1);

// GOOD
function addMonthToDate(month, date) {
  // ...
}
const date = new Date();
addMonthToDate(1, date);
