The next portion of the workshop is to review how to generate a random integer between two values.
|
||||
|
||||
Start by adding another `console.log()` that logs the message `"Now, generate a random integer between two values."` to the console.
|
||||
|
||||
In the next step, you will generate a random integer between the values of the `min` and `max` variables you have already created.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should have a `console.log()` that logs the message `"Now, generate a random integer between two values."`.
|
||||
|
||||
```js
|
||||
assert.match(code, /console\.log\((`|'|")\s*Now,\s+generate\s+a\s+random\s+integer\s+between\s+two\s+values\.\s*\1\);?/);

console.log(greeting);

The formula to generate a random integer between two values is the following:
|
||||
|
||||
```js
|
||||
Math.floor(Math.random() * (maximum - minimum) + minimum);
|
||||
```
|
||||
|
||||
This will produce a result that is a integer between two values.
|
||||
|
||||
Create a variable called `randomInt` and assign it the result of generating a value between the `min` and `max` values.
|
||||
|
||||
Then, log the `randomInt` variable to see the result. Try refreshing the page to see different results.
|
||||
|
||||
# --hints--
|
||||
|
||||
You should have a variable called `randomInt`.
|
||||
|
||||
```js
|
||||
assert.isNotNull(randomInt);
|
||||
```
|
||||
|
||||
Your `randomInt` variable should be a number.
|
||||
|
||||
```js
|
||||
assert.isNumber(randomInt);
|
||||
```
|
||||
|
||||
You should assign the result of generating a value between the `min` and `max` values. Make sure not to hardcode a value. You should use the formula provided above.
|
||||
|
||||
```js
|
||||
assert.isAtLeast(randomInt, min);
|
||||
assert.isAtMost(randomInt, max);
|
||||
|
||||
// check for whole random numbers just in case a camper does this
|
||||
assert.notMatch(code, /randomInt\s*=\s*\d+;?/);
|
||||
```
|
||||
|
||||
You should log the `randomInt` variable to the console.
|
||||
|
||||
```js
|
||||
assert.match(code, /console\.log\(\s*randomInt\s*\);?/);
|
||||
