Emojicode😎 (Variables)

#beginners #codenewbie #programming #tutorial

Part 2 of the Series on Emojicode.

Let's dive deep into coding with emojis.
In this part, I'll try to introduce you to what variables are and how are they implemented in Emojicode 💪.

Variable 🙄❓

A variable is simply a name that represents a particular piece of your computer’s memory that has been set aside for you to store, retrieve, and use data.
Variable store data types. We had a small introduction to strings in the last part - which is a data type!
Data types are just to tell computer what type of data it is.

Declaring and Assigning Variables:

Emojicode lets you declare two types of variables:

Declaring a constant variable:

🔤Earth🔤 ➡️ planet
💭🔜 planet is variable, ➡️ is assigning operator,  Earth is a string and is the value of planet variable 🔚💭

Declaring a mutable variable:

6 ➡️ 🖍🆕 coins
💭🔜 coin is a variable, ➡️ is assigning operator,  6 is an integer and is the value of coin variable, 🖍🆕 means mutable 🔚💭

💭 Mutable variables *need* to be mutated or emojicode will smash an error on you.

String Interpolation (printing your variable):

Just declaring variable is boring 🥱, we need to print them out.
To print variables, we need to wrap them around 🧲.

Arithmetic Operations:

Emoji	Operation	Example
➕	addition	2 ➕ 2 ➡️ number 💭 number is 4
➖	subtraction	2 ➖ 2 ➡️ number 💭 number is 0
✖️	multiplication	2 ✖️ 2 ➡️ number 💭 number is 4
➗	division	2 ➗ 2 ➡️ number 💭 number is 1
🚮	modulo	2 🚮 2 ➡️ number 💭 number is 0

Mutate the mutables 😎! Operator Assignments.

In Emojicode, operator assignment provides a short-hand method for modifying the value of variables.

Suppose we have a variable like this:

2 ➡️ 🖍🆕 mutate   💭 mutate is 0

Emoji	Operation	Example
⬅️➕	addition assignment	mutate ⬅️➕ 1 💭 mutate is now 3
⬅️➖	subtraction assignment	mutate ⬅️➖ 1 💭 mutate is now 2
⬅️✖️	multiplication assignment	mutate ⬅️✖️ 2 💭 mutate is 4
⬅️➗	division assignment	mutate ⬅️➗ 2 💭 mutate is now 2
🚮	modulo assignment
