In this JavaScript ES6 tips and walkthrough we take a look at How to Add Default Parameters in JavaScript ES6, Codecademy Programming, Default Parameters ES6 Tips. This is from Codecademy's JavaScript course, in the Functions section. The lesson is called Default Parameters and it teaches us how to set up default parameters in our JavaScript functions. To add default parameters in JavaScript functions, you assign the values of your parameters, similar to how you create a variable in JavaScript. Default Parameters is an ES6 feature and it allows us to give our function a default value in case no arguments are passed in when the function is run. Learning that you are able to set default values for your functions is a relief since there can be real-world cases in which your function is not passed in the arguments your function requires. Being able to assign values to your default parameters is important knowledge to have when learning to program in JavaScript.
