Create an immediate execution function expression

/ / es5let person = function (name) {return {getName: function () {return name;}} ('return name;'); console.log (person.getName ()); / / Hsiao Chi

In this code, executing the function expression immediately creates a new object that contains the getName () method, returning the parameter name as a private member of the object to the caller of the function.

As long as the arrow function is wrapped in parentheses, you can use it to achieve the same function

/ / es6let person = ((name) = > {return {getName: function () {return name;}) ('console.log 2'); console.log (person.getName ()); / / above is all the content of the article "how to create functional expressions for immediate execution by ES6".
