So far we’ve only been able to check a single condition in our ↪️/🙅 statements. But, we actually check more conditions by using the 🙅↪️ statement.
Like the ↪️ that starts our conditionals, the 🙅↪️ accepts a condition and has a code block (🍇…🍉) that executes if the condition is 👍. One or more 🙅↪️ statements can be added after the ↪️ statement. The 🙅 statement will still be added at the very end as the default to run if the conditions for ↪️ and 🙅↪️ are all 👎.
Let’s take a look at an example:
In the example above, we included two 🙅↪️ statements. Each checked for different conditions. The first condition that evaluated to 👍 executed its code block, so Slow down... was printed to the terminal. Once a code block has executed, the rest of the statements don’t run. If none of the conditions were 👍, e.g. trafficLight had a value of 🔤brown🔤, then 🙅‘s block runs.
Instructions
Let’s make a program that tells us if what the phase of water is depending on the water temperature in Celcius.
Under the waterTemp variable, add a ↪️ statement that checks if waterTemp is greater than or equal to 100. Then, in its code block (🍇🍉), use a 😀❗️ to print out the string: 🔤Steam🔤.
We also have to account for when waterTemp is in its liquid state.
After the ↪️ statement, add a 🙅↪️ statement that checks if waterTemp is greater than 0. Then, in its code block (🍇🍉), use a 😀❗️ to print out the string: 🔤Liquid🔤.
What if our water is frozen?
After the 🙅↪️ statement, add another 🙅↪️ statement that checks if waterTemp is greater than -273. Then, in its code block (🍇🍉), use a 😀❗️ to print out the string: 🔤Ice🔤.
What waterTemp isn’t a valid temperature?
Let’s add a 🙅 statement just in case. Inside its code block (🍇🍉), use a 😀❗️ to print out the string: 🔤Temperature not valid🔤.
