Explain variables in Node.js?
Answers
Variables are used to store values and print later like any conventional scripts. If “var” keyword is used then value is stored in variable. You can print the value in the variable using – console.log().

Eg:
$ node
> a = 30
30
> var b = 50
undefined
> a + b
80
> console.log(“Hi”)
Hi
