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.

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).
➕

It's because the string implementation grabs surrogates as well. I'll fix this sometime today, probably. – Conor O'Brien – 2016-09-25T18:28:17.507

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.

I used this for the infinite loop challenge. – Erik the Outgolfer – 2016-09-25T15:47:01.907

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

Some cases are:
⁉️❕ -> ❔0-10, 100 and i are ℹ, respectively.2-4 is done with ☺️, respectively.2-4 is done with 2-4 is done with n being 2-4 is done with n, use n➗. n is not a literal n, but the power of rooting. Erik the Outgolfer

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⏪⏬⏩

It seems like I've got the grasp of it... if anyone is wondering, the yes idea originated here.

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 .

I believe this bug is because JavaScript "123"+1 -> "1231". – Erik the Outgolfer – 2016-11-20T08:52:39.193
Please help popularise Emotinomicon, if you can. As it stands right now, only 2 people use it AFAIK (me and Conor O'Brien). – Erik the Outgolfer – 2016-09-25T15:42:40.287
1While this is an interesting idea, there isn't precisely much room for golfing in this language, except for perhaps changing program flow. Other than that, a lot of the tips that would apply here would apply to other languages with similar code layouts. – Conor O'Brien – 2016-09-25T15:45:45.323
@ConorO'Brien I know, but I have alerady posted 4 answers, and might post more. – Erik the Outgolfer – 2016-09-25T15:46:44.793
While that's true, half of them are interpreter bugs that I might fix in the future. – Conor O'Brien – 2016-09-25T15:48:20.147
@ConorO'Brien That's why I've said "right now". Also, there are currently 2 of them. – Erik the Outgolfer – 2016-09-25T15:54:02.610
Why the downvote? – acrolith – 2016-09-25T18:45:07.797
@daHugLenny I don't know, maybe it was a Community Autodownvote, or someone just not liking the simplicity of this post, or even someone who wants to just cost me rep (those guys get their votes removed). – Erik the Outgolfer – 2016-09-26T09:51:33.870
