Tried over a dozen times to get input to split no luck.

It works for individually letters and the strings added for examples how do I need to phrase the split join to work with this? https://code.sololearn.com/WG17dDhRUw6N/?ref=app

your approach is not quite there... consider this one: create a map of uppercase letters like so var letterMap = { "A": "๐Ÿ™‚", "B": "๐Ÿค“", ...... } now you can evaluate the input and create the encrypted word like so: var word = inputText.toUpperCase(); var encrypted = ""; for(var i = 0; i < word.length; i++){ encrypted += letterMap[word[i]] || word[i]; // the OR condition should take care of values not in the map (spaces for example) by simply putting the original value }

decrypting is a bit of an issue with emojis.... as the breakdown for individual emojis from a string of emojis fails but i found a solution online for this: https://stackoverflow.com/questions/24531751/how-can-i-split-a-string-containing-emoji-into-an-array first declare a function which breaks a string to array of emojis: var emojiStringToArray = function (str) { split = str.split(/([\uD800-\uDBFF][\uDC00-\uDFFF])/); arr = []; for (var i=0; i<split.length; i++) { char = split[i] if (char !== "") { arr.push(char); } } return arr; }; and replace the for loop with map on the returned array: emojiStringToArray(word).map(function(emoji,ind){ decrypted += letterMap1[emoji] || emoji; });

first of all, move the letter map outside of the function, no need for it to be inside secondly, after using getElementById(..) you also need the value, so change it to getElementById(..).value and lastly, you'd want to put the output somewhere, so i assume that,s what the <p> is for? document.getElementById("a").innerHTML = encrypted; should do the trick

Thanks for the detailed explanation Morpheus I noticed it was considering an emoji as more than a single character I now know why. If you can help fix the original switch method that would be awesome I love how there are many ways to accomplish things in coding.

Thank you Burey I tried a map method before this hopefully your advice will make it work.

in case function provided by Burey is unclear, here's the breakdown java script uses utf16 character encoding of 16 bits for simple characters , but emojis need 20 bits ,for example A is 0041 in hexadecimal ( 16 bits) but ๐Ÿ˜ is 1F600 in hexadecimal ( 20 bits), so , to handle emojis we break 20 bits in a way of two 16 and 16 bits called surrogate pairs , so that we can use them in utf-16 mode, example ๐Ÿ˜ 1F600(20 bits) is broken to D838 and DE00, both 16 bits, used side by side to make ๐Ÿ˜, can try this on ur console to be sure "\uD838\uDE00" gives output ๐Ÿ˜ String.fromCodePoint(0x1F600) also gives output ๐Ÿ˜ now back to ur issue , try checking this on ur js console "๐Ÿ˜". length and it will return 2 instead of 1 , so emojis are made up of 2 characters instead of 1 in utf-16. Bobbie when I give input of ๐Ÿค“๐Ÿค“๐Ÿค“ in ur decryption area, you know the loop runs actually 6 times instead of 3 in ur function1, moreover emojis are not even read hence they are undefined , and the backup part - || words[ i ] simply returns the user input without decryption. so there's 2 ways to solve ur problem first the fundamental , awesome to know but complex way as provided by Burey or a simple way , of a separate switch block in ur function1 for every emojis,

finally I am at peace with this problem with a perfect one liner solution, ditch the switch, ditch the regex , ditch the function Behold the ES6 voodoo for emoji parsers. ######################### [..."๐Ÿ˜๐Ÿค“๐Ÿ˜๐Ÿค“๐Ÿ˜๐Ÿค“๐Ÿ˜๐Ÿค“๐Ÿค“"] ######################### that's it , https://code.sololearn.com/WroSj17hdHKG/?ref=app

[..." Ur emoji string here" ] , this syntax parses emojees into arrays that's it now u have a emoji array, and no need to worry about layers and layers of regex , or about codepoints for various emojis!, just need ES6 supported browsers, that mostly are, thx to burray for that stackoverflow link

@Bobbie, this code is a strong contender for COTD , because of it cool concept, simple code, yet with subtle complexities involved in implementation. I learned few simple but effective tricks like better way to use inputs and to use || this for fallback , since coming from c and C ++ background , I couldn't follow ES features in my coding practice

Awesome Morpheus I would love a team to try to conquer this Burey is busy with work and all but I assured him if we get this up and running and it becomes profitable he will not be forgotten. Are you on Discord or Slack so we can chat more?

Morpheus do you have app building experience? I think this might make a fun one. I have been trying but my Android Studio continues to have gradle issues.
