Let’s now expand the use of our conditionals to account for other types like: 🔤, or 🔢, or 💯! But there’s a question of, “how do we convert the types 🔤,🔢, and 💯 to 👌 values?” Well, that’s where the 🙌 comes in!
🙌 compares two values, one on its left side and one on its right side, to see if they have the same value. The entire piece of code is an expression, we can think of expressions as code that evaluates to a value. In this case, the expression evaluates back to a 👍 or 👎 value.
Let’s see a few examples:
100 🙌 100 💭 Evaluates to: 👍
100 🙌 101 💭 Evaluates to: 👎
32.1 🙌 32 💭 Evaluates to: 👎
4.2 🙌 4.2 💭 Evaluates to: 👍
🔤A🔤 🙌 🔤A🔤 💭 Evaluates to: 👍
🔤A🔤 🙌 🔤B🔤 💭 Evaluates to: 👎
🔤A🔤 🙌 🔤a🔤 💭 Evaluates to: 👎 Read through the examples and make sure you understand how the comparison works. Let’s also take a look at the 🙌 usage in a conditional:
↪️ 🔤coke🔤 🙌 🔤pepsi🔤 🍇
😀 🔤They're the same thing🔤❗️
🍉
🙅 🍇
😀 🔤They're NOT the same🔤❗️
🍉In the example above, our condition is the expression 🔤coke🔤 🙌 🔤pepsi🔤. Since the strings are not the same, they're NOT the same is printed to the terminal.
Under the declared variables enteredPIN and correctPIN, add a ↪️ statement that checks if enteredPIN and correctPIN are the same string using the 🙌 operator.
Inside the 🍇 🍉 block, add a 😀❗️ to print out 🔤Access granted🔤.
We should also add an else statement using 🙅. Inside this 🍇 🍉 block, use 😀❗️ to print out 🔤Access denied🔤.
