//Control flow or Conditional statements//

//Remember truthy and falsey 0, NaN, null, false, undefined, and empty strings//
//are false and will make your conditional statement false//

//if, else if, else  Statements//

/* If and else statements work together to evaluate a logical expression
* and run different statements based on the result. if statements
* can be used alone but an else statement must be used with an if.
* The proper setup for an if statement is
* if(condition) {
* block of code executed if true
*  } */
function example(num1, num2) {
  if(num1 > num2) {
    return num1 + ' is greater than';
  }else if(num2 > num1) {
    return num2 + ' is greater than';
  }else {
    return "Welp, I tried!"
  }
}

console.log(example(3,3)); // will return "Welp, I tried!" since the//
//arguements are equal and neither is greater//


//Switch Statements//

/* Switch statements chooses between multiple statements (cases) to execute
* based on possible values of a single expression. A break statement
* should end the case. You can run 1 block of code for multiple cases.
* The poper setup for a switch statement is
*
* switch (epression) {
*   case value:
*     statement;
*     break;
*   case value:
*     statement;
*     break;
*  }
