object destructuring

Functions in JavaScript can only return a single value using the return statement. So, how can we simulate returning multiple values from a function? When we have the need to return multiple values, we can utilize a couple of tricks to achieve this.

Initially, I attempted to destructure the object using the following syntax: const { name, age } = body.value; However, I encountered an issue when trying to add types to the destructured variables: const { name: string, age: number } = body....

How Object Destructuring Works Consider the following example: const person = { firstName: 'Tom', lastName: 'Cruise', actor: true, age: 57 }; To extract specific properties from the person object and assign them to variables, you can use object destructuring:...
