Understanding default parameters and rest parameters is crucial for writing flexible, maintainable javascript functions. these es6 features make your code more robust and easier to read. We can add a default value directly in our parameter list. here, we need to watch out for order. defaulted parameters should only occur at the end after any parameters that do not have defaults:. Rest parameters in javascript allow us to accept a variable number of arguments as an array. javascript introduced this feature in es6. it is now the preferred way to access the variable number of arguments. before rest parameters, the only way to do this was to use the arguments object.
