Variables are never created inside variables. variables contain things called objects like strings, integers or floating numbers or any sort of input. For example, Greeting = input("What's up?") here, 'Greeting' is the variable and it contains the string the user responds with to the question "What's up?"

Another example, Greeting = "Welcome to Palm City Beach!" here, 'Greeting' is still the variable but it contains a different value. Instead of an input, it contains a string.

Btw, strings are just alphanumeric characters and r always enclosed in quotation marks.

For example, firstName = input("what is your first name?") print( "Hi my name is", firstName)

in the function print, the string is "Hi my name is" and 'firstName' is the variable.

You might say that object properties are "variables inside of other variables". For example, "name" and "age" are both inside "person":

var name = "Joe";
var age = 22;
var person = { name, age };
console.log("The person's name is " + person.name);
console.log("and they are " + person["age"] + " years old.");

But I'm not sure that was the original question since I don't see how it would relate to this video.
