I have a x variable with the following content inside:

x = [ {
    id: '1',
    name: 'name,
} ]

And I thought that to access id was x.id , but it is not so. How to access?

There you have an object inside an array . First you access the index of the element (in case it only has one, then it is 0), then it accesses the member of the object, as it did correctly.

x = [ {
    id: '1',
    name: 'name',
} ]
document.body.innerHTML += x[0].id;

In the assignment of a value the brackets delimit an array . The keys delimit an object.

Just as curiosity would also work x[0]["id"] since in JavaScript an object is actually an associative array .
