Challenge Use Conditional Logic with If Statements

We can use if statements in JavaScript to execute code only if the specified condition is met.

Each if statement requires a boolean condition to evaluate. If the boolean evaluates to true, the statements inside the curly braces will execute. Otherwise, if it evaluates to false, the code will not execute.

Example

function trueOrFalse(myVal) {
  if (myVal > 10) {
     return "Greater Than";
  }
  return "Not Greater Than";
}

If myVal is greater than 10, the function will return "Greater Than". If it is not, the function will return "Not Greater Than". Both return statements will never get executed because as soon as the first one is encountered, the execution exits the function and returns control to where the function was called.
