js variables
//Making variables with let:
let numberOfFriends = 1;
//Incrementing:
numberOfFriends += 3; //numberOfFriends is now 4
// Variables with const
const minimumAge = 21; //CANNOT REASSIGN!
//Booleans - true or false values
true;
false;
let isHappy = true;
//Naming Conventions
// Use upper camel-cased names:
let numberOfChickens = 6; //GOOD
// NOT THE JS WAY:
// let number_of_chickens = 6;js variable html
<div onload="document.innerHTML(name + ' is ' + age)">js var
var a = 'A';
var b = a;
// è come dire:
var a, b = a = 'A';js var
var a = 1;
b = 2;
delete this.a; // Genera un TypeError in strict mode. Altrimenti fallisce senza generare messaggi.
delete this.b;
console.log(a, b); // Genera un ReferenceError.
// La proprietà 'b' è stata cancellata e non esiste più.html define javascript variable
