Strings
Create a function that takes a string and returns true if no character appears twice, false otherwise.
function isUnique(string) {
let knownChars = "";
for (let char of string) {
if (!knownChars.includes(char)) {
knownChars += char;
} else {
return false;
}
}
return true;
}// Since Node 10, we're using Mocha.
// You can use `chai` for assertions.
const chai = require("chai");
const assert = chai.assert;
// Uncomment the following line to disable truncating failure messages for deep equals, do:
// chai.config.truncateThreshold = 0;
// Since Node 12, we no longer include assertions from our deprecated custom test framework by default.
// Uncomment the following to use the old assertions:
const Test = require("@codewars/test-compat");
