With the release of ECMAScript 6 (ES6), JavaScript developers were introduced to a variety of new features that have made coding in JavaScript more efficient and expressive. One of these features is the ES6 object shorthand syntax. This feature allows developers to write less code while still achieving the same functionality. In this blog post, we’ll explore the beauty of ES6 object shorthand and how it can help us write more concise and readable code.

What is ES6 Object Shorthand?

ES6 object shorthand is a syntax that allows us to define object literals with less repetitive code. Instead of specifying both the key and value for each object property, we can use a shorter syntax that only requires us to provide the variable name if it matches the key. This shorthand notation makes our code cleaner and more concise.

Traditional Object Literal Notation

Before ES6, when defining an object literal, we had to explicitly assign values to each property using the following syntax:

const name = "John";
const age = 30;

const person = {
  name: name,
  age: age,
};

ES6 Object Shorthand

With ES6 object shorthand, the code above can be simplified to:

const name = "John";
const age = 30;

const person = { name, age };

Using the shorthand syntax, JavaScript automatically assigns the value of the variables with matching names to the corresponding object properties. This eliminates the need for repetitive code, making our code more readable and maintainable.

Computed Property Names

ES6 object shorthand also supports computed property names. This means we can provide an expression inside square brackets to dynamically define the property name. Here’s an example:

const key = "color";
const value = "blue";

const obj = {
  [key]: value,
};

In the code snippet above, the property color is dynamically assigned to the object obj using the value of the key variable.

Conclusion

ES6 object shorthand is a powerful feature that allows JavaScript developers to write less code and achieve the same functionality. By eliminating repetitive syntax and supporting computed property names, it enhances code readability and reduces the chances of human error. So, the next time you’re writing JavaScript code, consider leveraging ES6 object shorthand to make your code cleaner and more efficient.
