Exercise 3

Modify the age.js program you wrote in the exercises for the Variables chapter. The updated code should ask the user to enter their age instead of hard-coding the age in the program. Here's an example run:

How old are you? 22
You are 22 years old.
In 10 years, you will be 32 years old.
In 20 years, you will be 42 years old.
In 30 years, you will be 52 years old.
In 40 years, you will be 62 years old.

Solution

let readlineSync = require('readline-sync');
let age = readlineSync.question('How old are you? ');
age = parseInt(age);
console.log(`You are ${age} years old.`);
console.log(`In 10 years, you will be ${age + 10} years old.`);
console.log(`In 20 years, you will be ${age + 20} years old.`);
console.log(`In 30 years, you will be ${age + 30} years old.`);
console.log(`In 40 years, you will be ${age + 40} years old.`);

Code Blocks

You can write code blocks using three backticks (```) followed by the language you want to show. For instance, if you wanted to write a Ruby code block you would write:

```ruby
class Foo
end
```

class Foo
end

You can also leave out the language identifier, doing this will make it so your code isn't highlighted at all, and all text will be white with no coloring.

```
class Bar
end
```

class Bar
end

Highlighting

You may highlight lines within your code blocks. This is a different type of highlighting, and isn't related to how the code within your code block may be colored depending on the language identifier used.
To highlight one or more lines of code, add # highlight on a separate line just before the first line you wish to highlight. To end highlighting, add # endhighlight on a separate line immediately after the last line you wish to highlight.

```ruby
def say_hello_world
# highlight
  puts 'Hello World!!!'
# endhighlight
end
```

def say_hello_world
# highlight
  puts 'Hello World!!!'
# endhighlight
end
