Log("Payment is done") }) doPayment() =>Payment is done //oops bad, we are doing second time! doPayment() =>undefined! The above code snippet showcases the function doPayment that is wrapped over once will be executed only once regardless how many times we call them! The once is a simple but effective function in our toolkit! Memoize Function Before we close this exciting section, let’s see my favorite function called memoize. We know that the pure function is all about working on its argument and nothing else.
Js function in functional-playground directory. js file. But how are we are going to call this function, which resides in a different file? Gist on Exports ES6 also introduced the concept called modules. ES6 modules are stored in files. js file itself as a module. Along with the concept of modules came imports and exports statements. In our running example, we have to export the forEach function so that others can use them. So that we can change the following code into Listing 2-10. js file. Gist on Imports Now that we have exported our function as you can see in Listing 2-10, let’s go and consume it via import!
