ECMAScript 6 Arrow Function That Returns an Object
ECMAScript 6 (ES6) introduced arrow functions, which provide a concise syntax for writing JavaScript functions. One of the advantages of arrow functions is that they can simplify the process of returning objects. In this blog post, we will explore how to use arrow functions to return objects in ES6.
Using the Arrow Function Syntax
The arrow function syntax allows us to write shorter and more readable code. To return an object using an arrow function, we can wrap the object literal in parentheses. Here’s an example:
const getObject = () => ({ prop1: 'value1', prop2: 'value2' });
console.log(getObject());
In the above code snippet, we define an arrow function called getObject
that returns an object literal with two properties: prop1
and prop2
. The object literal is wrapped in parentheses to indicate that it should be returned. Finally, we call the getObject
function and log the returned object to the console.
The output of the above code will be:
{ prop1: 'value1', prop2: 'value2' }
Using the Explicit Return Statement
Alternatively, we can also use the explicit return statement with arrow functions to return an object. Here’s an example:
const getObject = () => {
return { prop1: 'value1', prop2: 'value2' };
};
console.log(getObject());
In this code snippet, we define the getObject
arrow function using the explicit return statement. Inside the function body, we use the return
keyword to return an object literal with two properties. Finally, we call the getObject
function and log the returned object to the console.
The output of the above code will be the same as before:
{ prop1: 'value1', prop2: 'value2' }
Conclusion
Arrow functions in ECMAScript 6 provide a concise and readable way to return objects. Whether you choose to use the arrow function syntax or the explicit return statement, both methods allow you to easily return objects in your JavaScript code.
By leveraging the power of arrow functions, you can write cleaner and more efficient code. So go ahead and start using arrow functions to return objects in your ES6 projects!
