You can also assign a value to the variable when you declare it: var carName = Volvo; In the example below, we create a variable called carName and assign the value Volvo to it.alue = undefined. In computer programs, variables are often declared without a value. The value can be something that has to be calculated, or something that will be provided later, like user input. A variable declared without a value will have the value undefined.
