const x = 7;
const y = 4;

(x == 7 && y == 5); // false
(x == 3 && y == 4); // false
(x == 7 && y == 4); // true

if (condition == value && condition == otherValue) {
  return something;
}//|| is the or operator in JavaScript
if(a == 1 || b != 'value'){
    yourFunction();
}var a = 2;
var b = 5;
var c = 10;

if (a === 3 || a === 2) {
	console.log("TRUE");
} else {console.log("FALSE");}
if (a === 4 || b === 3 || c === 11) {
	console.log("TRUE");
} else {console.log("FALSE");}
if (b === 5 || c != 10) {
	console.log("TRUE");
} else {console.log("FALSE");}

TRUE
FALSE
TRUE
*//*OR operator:*/

// example:
var a = 10;
var b = 5;

if(a > 7 or b > 7){ 
  print("This will print!")
}
// Even though a is not less than 7, b is, so the program will print
// the statement.
