var let const javascript
Const vs Let vs Var
const pi = 3.14
pi = 1
cannot do this becuase with const you cannot change the value
_____________________________________
Let --> is block level
for(let i = 0; i < 3; i++) {
console.log(i) --> it will console here
}
console.log(i) ---> Not here
---------------------------------------
Var is for variables available to the entire function
for(var j = 0; j < 3; j++) {
console.log(j) --> it will console here
}
console.log(j) ---> it will console here
