Aliases with JavaScript Destructuring | Javascript

 
//There are cases where you want the destructured variable to have a different name than the property name

const obj = { 
  name: "JSsnippets"													
};


// Grabs obj.name as { pageName }
const { name: pageName } = obj;

//log our alias
console.log(pageName) // JSsnippets

This code snippet demonstrates object destructuring with aliasing in JavaScript. 1. The object `obj` is defined with a property named `name` with the value `"JSsnippets"`. 2. The following line uses object destructuring to extract the `name` property from the `obj` object and renaming it to `pageName`. ``` const { name: pageName } = obj; ``` 3. As a result, the variable `pageName` now holds the original value of `obj.name`, which is `"JSsnippets"`. 4. Finally, when we output the value of `pageName` using `console.log()`, it will print out `JSsnippets`. So, in this example, we are extracting a property from an object and assigning it to a variable with a different name using object destructuring.
