Tips for golfing in Emotinomicon

Question

What general tips do you have for golfing in Emotinomicon? I'm looking for ideas that can be applied to code golf problems in general that are at least somewhat specific to Emotinomicon (e.g. "remove comments" is not an answer).

Please post one tip per answer.

Answer 1

Should be answers to respective challenges (if they exist). Note that some of these code samples might alerady be answers somewhere else.

If you just want to print undefined, use this 4-byte, 1-char program.

😨

Infinite loop (6 bytes, 2 chars).

ℹ⏩

Cat (owned by Conor O'Brien) (15 bytes, 5 chars).

⏫⏪⏬⏫⏩

This program should output the 8 phases of the moon, but it doesn't seem to work (61 bytes, 16 chars).

😭🌘🌗🌖🌕🌔🌓🌒🌑😲⏪⏬😷⏩😀😬

Hypothenuse (27 bytes, 7 chars).

😼😣😼😣➕😋😨

Answer 2

If you just want a truthy value (or even just a value), without using it, use ℹ. It's 3 bytes, while the others are 4 bytes.

Answer 3

If you want to output 2 chars or less, do not use ⏪⏬⏩, use the number of ⏬s needed.

Answer 4

Infinite Looping

If you want to loop a program infinitely, from index n, you can use n😬 to jump behind the nth character. For example, this 34-byte, 12-char program for yes:

🔟⏪😭sey😲⏪⏬⏩🔟⏩

Becomes this 32-byte, 11-char program:

🔟😭sey😲⏪⏬⏩😀😬

Answer 5

Make use of built-ins.

Some cases are:

• ⁉️❕ -> ❔
• The numbers 0-10, 100 and i are 😀😅😉😍😒😗😜😡😁😆🔟💯ℹ, respectively.
• Multiplication with 2-4 is done with 😇☺️😏, respectively.
• Division with 2-4 is done with 😔😙😞, respectively.
• Exponentiation with 2-4 is done with 😣😃😈, respectively.
• Rooting:
  • n-Rooting with n being 2-4 is done with 😋😐😕, respectively.
  • For other n, use 😅n➗😘. n is not a literal n, but the power of rooting.

Answer 6

Because of a bug in the interpreter, if you want to append 1 to a number (e.g. 10 -> 101), use 😄. As it is right now, you have to use 😅➕ for the true function of 😄.
