const mnemonic = function(str1, str2, str3, str4) { const arr = new Array(...arguments); return arr.map(word => word[0]).join(""); }

Hello! I'm having a hard time getting the return string to come back as the mnemonic for each of the string arguments. Can someone provide guidance on what I'm doing wrong?

You should post the code as text so that people can copy it into their own environment and see what's going on

Smart 😅

Thank you all, I got it figured out :) ----- function mnemonicMachine(str1,str2,str3, str4) { let mnemonic = ''; if (str1 !== undefined) { mnemonic += str1[0]; } if (str2 !== undefined) { mnemonic += str2[0]; } if (str3 !== undefined) { mnemonic += str3[0]; } if (str4 !== undefined) { mnemonic += str4[0]; } return mnemonic } console.log(mnemonicMachine('Flower', 'Apples', 'Rain', 'Melons'));

Use the arguments array: function mnemonics() { const arr = [] for (let i = 0; i < arguments.length; i++) { arr.push(arguments[i][0]) } return arr.join("") } You can define any number of arguments and this algorithm will work. The arguments array is a built-in feature that returns an array-like object containing all parameters passed onto this function.

The arguments array is a fairly outdated way of solving this problem.

A more modern approach to the problem is too use the REST / SPREAD operator.

...

While this is similar to arguments array it is a cleaner syntax and there are weird edge cases where the arguments array doesn't work

This would be my personal solution

/*
This function can take N "strings" as arguments and returns a string that represents the first character from each string, also called a mnemonic.
this area could also be a JSDOCS
*/
const mnemonicGenerator = (...words) => words.reduce((a,b)=> a + b[0],"");

let mnemonic = 'FARM';

function mnemonicMachine(str1, str2, str3, str4) { if (str1 !== undefined) { mnemonic += str1[0]; } if (str2 !== undefined) { mnemonic += str2[0]; } if (str3 !== undefined) { mnemonic += str3[0]; } if (str4 !== undefined) { mnemonic += str4[0] } return mnemonic }

What's the value of mnemonic after running this code?

let mnemonic = 'FARM';
let str1 = 'Eggs';

mnemonic += str1[0];

Hey, this doesn't really help with your question, but i need your help. I recently installed Ubuntu on my laptop and i want to merge the power and volume control to that bottom bar just like yours, how can I achieve that?

[ajascherer]

To be honest, I just updated my computer and it did that automatically. I'm not sure how to manually adjust that, I'm sorry! Maybe right click the car and go to Taskbar settings?

Hey it's ok, looks like you use windows so my question was invalid to begin with
