string

Can someone answer this for me please.

Why in the alert function why would you put (name + "Sam" + age); Why wouldnt you just put Sam is 26?

Var name = "Sam" var name = "26" alert(name + " Sam " + age);

Perhaps a bigger question is if name = "Sam", why would you put name + "Sam"? Won't that be redundant?

But the reason you would put "Sam" + age" instead of "Sam is 26" is that it allows you to display a different age just by changing the value of the variable. I know it doesn't seem like a big deal in this simple example, but in more practical programming situations you will often need to display a variable instead of something permanent in a string.
