function scramble(str1,str2) {
let result;
for(let i = 0; i < str2.length; i++){
let found = str1.match(new RegExp(str2.charAt(i)));
if(found === null){
result = false;
break;
} else {
str1 = str1.replace(found, "");
result = true;
}
}
return result;
}
The purpose of this function is to verify if the letters of the second string are contained in the first string and can be rescrambled to create the the word:
scramble('rkqodlw', 'world'); //true
scramble("scriptjavx", "javascript"); //false
scramble('katas', 'steak'); //false
The above is working but I am looking to improve the performance time to less than 12000ms for for any given string.

Why isscramble("scriptjavx", "javascript"); //false
? Letters can be used only once?

yes, letters can only be used once because they have to be able to be rearranged to create input string
