The keyword `if` tells JavaScript to execute the code in the curly braces under certain conditions, defined in the parentheses. These conditions are known as `Boolean` conditions and they may only be `true` or `false`. When the condition evaluates to `true`, the program executes the statement inside the curly braces. When the Boolean condition evaluates to `false`, the statement inside the curly braces will not execute. **Pseudocode**
if (condition is true) {
  statement is executed
}
**Example** ```js function test (myCondition) { if (myCondition) { return "It was true"; } return "It was false"; } test(true); test(false); ``` `test(true)` returns the string `It was true`, and `test(false)` returns the string `It was false`. When `test` is called with a value of `true`, the `if` statement evaluates `myCondition` to see if it is `true` or not. Since it is `true`, the function returns `It was true`. When we call `test` with a value of `false`, `myCondition` is *not* `true` and the statement in the curly braces is not executed and the function returns `It was false`. # --instructions-- Create an `if` statement inside the function to return `Yes, that was true` if the parameter `wasThatTrue` is `true` and return `No, that was false` otherwise. # --hints-- `trueOrFalse` should be a function ```js assert(typeof trueOrFalse === 'function'); ``` `trueOrFalse(true)` should return a string ```js assert(typeof trueOrFalse(true) === 'string'); ``` `trueOrFalse(false)` should return a string ```js assert(typeof trueOrFalse(false) === 'string'); ``` `trueOrFalse(true)` should return the string `Yes, that was true` ```js assert(trueOrFalse(true) === 'Yes, that was true'); ``` `trueOrFalse(false)` should return the string `No, that was false` ```js assert(trueOrFalse(false) === 'No, that was false'); ``` # --seed-- ## --seed-contents-- ```js function trueOrFalse(wasThatTrue) { // Only change code below this line // Only change code above this line } ``` # --solutions-- ```js function trueOrFalse(wasThatTrue) { if (wasThatTrue) { return "Yes, that was true"; } return "No, that was false"; } ```
