How to create an array with multiple children in JavaScript?

In JavaScript, you can create an array with multiple children by simply defining an array and then adding elements to it using the push method, or by defining the array with the elements already included. Here are some examples:

Using the push method:

const myArray = [];
myArray.push("child1");
myArray.push("child2");
myArray.push("child3");
console.log(myArray); // ["child1", "child2", "child3"]

Defining array with elements:

const myArray = ["child1", "child2", "child3"];
console.log(myArray); // ["child1", "child2", "child3"]

You can also create an array of arrays to have multiple levels of children. Here's an example:

const myArray = [["child1", "child2"], ["child3", "child4"], ["child5", "child6"]];
console.log(myArray); // [["child1", "child2"], ["child3", "child4"], ["child5", "child6"]]

In this example, myArray contains three arrays, each with two children. You can access individual elements of this multi-dimensional array using indexing, like this: myArray[0][1] would return "child2".
