Access 🔑

Now that we know how to define objects, let's start to use them

The dot opperator . (property accessor)

Let's start with getting values from them. Well, turns out you already have been doing it a lot, remember console.log ?

The . here is accessing the property log from the console object.

Taking the previous example transaction object, we can access properties from it using . same way we got the log function:

let transaction = {
  currency: 'EURO',
  amount: 77.5,
  cashPayment: false,
}

console.log(transaction) // Will log the whole transaction
console.log(transaction.amount) // will only log the amount of the transaction

Accessing a property with . only give you it's value, and because it is a value you can use it like any other values:

let taxes = 1.2 // let's define 20% taxes
let transaction = {
  currency: 'EURO',
  amount: 77.5,
  cashPayment: false,
}

const totalWithTaxes = transaction.amount * taxes

console.log(totalWithTaxes) // will log 93 (77.5 * 1.2)

Instructions

We will provide a human variable of type object just like the one you did in the previous exercise

Your job will be to decompose each property in its own variable:

• define a name variable with the value of the name property of the human variable
• same for age
• and same for secureLuggage
