Every statement ends
Like a full stop at the end of a sentence. Without it, the compiler cannot tell where your statement stops.
DOCUMENTATION
The syntax, symbol by symbol.
Emoji Script replaces the keywords of a programming language with emojis. Everything else stays the same: variables, conditions, loops and statements read from top to bottom. This page gathers every symbol of the language, what it replaces and how to put them together.
THE BASICS
Six rules and you can read any script.
Blocks open and close
Everything between the open padlock and the closed padlock belongs to the condition or to the loop.
Text goes between quotes
Everything between these two emojis is printed as is, emojis included.
Moons are parentheses
They wrap a condition or whatever you want to print.
The finger announces the block
It sits between the condition and the block that follows it.
Names stay in letters
Variables are written with regular letters: score, age, message.
REFERENCE
Every symbol of the language.
On the left the emoji, in the middle its equivalent in a classic language, on the right what it does.

If the condition between the moons is true, the first block runs. Otherwise the 🙃 block does.

As long as i is smaller than 6, the block runs. The last line moves the counter forward; without it the loop would never stop.
The length of a text

📏 counts characters. Careful: an emoji often takes two characters for the browser.
TROUBLESHOOTING
The error messages, translated.
Unclosed string: add 🤫 at the end of your text.
You opened a text with 💬 without closing it with 🤫. The compiler then reads the rest of the script as text.
Unknown symbol near …
A character is not part of the language. It is often a lookalike emoji, for example 🌙 instead of 🌜, or a plain digit stuck to an emoji.
Execution stopped after 2 seconds
Your 🔁 loop never ends. Check that the tested variable really changes inside the block, for example with i➡️i➕1️⃣🙏.
Forbidden identifier
Some names reserved by the browser are blocked for security reasons. Pick another variable name.
