So now you might ask, how do we print the value of a constant to the terminal? Oftentimes, we find ourselves needing to print constant values as part of a message in the terminal. In these cases, we can use string interpolation.
String interpolation can be used to construct a string from a mix of constants, variables, and others by including their values inside a string literal.
In Emojicode, to insert a value into a string using string interpolation, we can write the variable inside two
🧲s and it will print its value.
Suppose we have a constant named
height with a value of
3000, and we want to use string interpolation to print out a fun fact:
3000 ➡️ height 😀🔤Alex Honnold climbed El Capitan, which is 🧲height🧲 feet, without a rope!🔤❗️
It will output:
Alex Honnold climbed El Capitan, which is 3000 feet, without a rope!
Output the constant

The current year is [year]
[year] is the value of
