Compares Two Different Strings Characters (JS)

Question

Let's say I have:

string1 = "abcdefgh"
string2 = "abb"

I want to compare all the characters in string2 and check they are represented in string1

Examples:

// Example 1
string1 = "abcdefgh"
string2 = "abb" 
// -->TRUE (even though "b" is used twice it checks it twice to make sure")

// Example 2
string1 = "abcdefgh"
string2 = "abz"
// FALSE ("z" is not represented in string1)

// Example 3
string1 = "abcdefgh"
string2 = "ddd"
// TRUE

// Example 4
string1 = "abcdefgh"
string2 = "xyz"
// FALSE

Thank kindly

this should solve

const string1 = "abcdefgh"

const string2 = "abb"

const result = string2.split('').every(letter => string1.includes(letter))
console.log(result)

transform string2 into array validates if any item in the array is in string1

I like your one-liner. If he can fix this to solve his problem, he has every right to use it. – HEllRZA Jul 08 '22 at 23:18
@MisterJojo what error did you find – EvoluWil Jul 10 '22 at 14:20
@MisterJojo I wrote that it needs fixing. And I hinted the solution :) Sry 4 playing games. Fix: `some` -> `every` – HEllRZA Jul 10 '22 at 20:49
@MisterJojo Damn I'm quite sure you got it, but not completely Try to fix the code: `const str2conpare =(s1,s2)=>[...s2].every(l=>s1.includes(l));` as we want every char in s2 to be in s1, not just some. – HEllRZA Jul 11 '22 at 06:29
@HEllRZA tell me something I don't know... and I am Not the PO, so, I can't change the original part of his post – Mister Jojo Jul 11 '22 at 11:33
@WillianGit not you should have all the info. – HEllRZA Jul 11 '22 at 11:59
@MisterJojo I really got it wrong, I'll fix it – EvoluWil Jul 11 '22 at 16:25
