EXAMPLE -
Create a variable and assign your age
var myage = 32;
type your age:
console.log(my age) ;
Notice that we did not type the actual numeric age. We used the variable instead. There wouldn’t be any purpose of declaring a variable if we were going to type 32 directly.
This makes the scrip more portable which means that the result on the screen is independent of the code console.log(myAge); . If we need to change our age all we have to do is to assign another number to the variable myAge and the output will change automatically. That’s the purpose of a variable.
