//let and var are both editable variables and can be changed later on in your program;
let dog = 'Woof';
//dog is equal to the string 'Woof';
dog = false;
//You can changed the value of dog now because it was defined with let and not const;
let cow = 'Moo';
//cow is equal to the string 'Moo';
cow = true;
//You can change the value of cow later on because it is not defined with const;
//const is used when declaring a variable that can't be changed later on -- const stands for constant;
const pig = 'oink';
//This assigns the string 'oink' to pig which can not be changed because it is defined with const;
pig = 'snort';
//Above throws an error
//Good Job you now know how to declare variables using JavaScript!!!

//choose the best for your solution
var myVariable = 22; //this can be a string or number. var is globally defined
let myVariable = 22; //this can be a string or number. let is block scoped
const myVariable = 22; //this can be a string or number. const is block scoped and can't be reassigned

////We can define variables in 3 ways {var,let,const}///////
////syntax- var variable_name=value;
///// let variable_name=value;
/////const variable_name=value;
var myfristvariable="neha jaiswal";
const mysecondvariable=80;
let mythirdvar=abc;

// you an pass in strings or a number

//variables are a way to easily store data in javascript
//variables are declared by the var keyword, example...
var x = 10;
//or
var dog_name = "daisy";
//which can also be written as
var dog_name = 'daisy';
//same thing with single quotes and double quotes
