Exercise 05 - joinStrings

Step 1: Learn

First, look at the example code in joinStrings-example.js. Try and predict what the console.log output will be. When you're ready, run the test:

npm test joinStrings-example.spec.js

If you saw anything unexpected, feel free to review the code again.

Step 2: Do

After understanding the example code, you will recreate the snippet on your own using the following instructions (in joinStrings.js):

Create 4 variables: firstName, lastName, thisYear, and birthYear
Create a 5th variable, greeting, that is constructed from the previous 4 variables

It should contain a greeting that includes the person's full name and age

Note: To make the tests pass, you will need to use exact values and wording (as you will see described in joinStrings.js). If the tests fail, look at the feedback in your terminal then check your spacing, capitalization, and punctation.

Step 3: Optimize

You will edit your code to make it easier to read using the following instructions:

Create 2 new variables: fullName and age

Do NOT simply type the full name and age into the new variables
Instead, use the pre-existing variables, with the calculations that are currently inside of greeting

Edit the greeting string to use fullName and age instead of the other 4 variables

greeting should look something like:

"Hello! My name is " + fullName

Run all the tests one last time to ensure that the output remains unchanged:

npm test joinStrings.spec.js

Hints

Look at the docs for JavaScript variables for a quick reference.
Refer back to the Variables and Operators lesson if you are still stuck.
