Care, here you are doing a console log inside a loop, so you will print something at every round of the loop. It is a good idea to start from letter which is empty and add letters to it ! The console log should be right after ;)

for(i = hacker2.length; i >= 0; i--) {
console.log(lettres += hacker2.charAt(i))

Here, lettres has kept in memory the hacker1 letters because the scope is the same and you use +=. Maybe try this in to separate functions or assign a new variable, or start back letter empty :-)

}

// Lexicographic order
if (hacker1.localeCompare(hacker2) > 0) {
console.log("The driver's name goes first");
} else if (hacker1.localeCompare(hacker2) === 0) {
console.log("What?! You both got the same name?");
} else {
console.log("Yo, the navigator goes first definitely");
}

// Palindroms
var userString = prompt("Enter a string");

newString = "";
n = userString.length;
for(i = n-1; i >= 0; i--) {
newString += userString.charAt(i);
} if (newString == userString) {
console.log("This is a palindrome.");
} else {
console.log("This is not a palindrome.")

POUR .search() / Si la recherche aboutit, search() renvoie un entier qui correspond à l'indice de la première correspondance trouvée dans la chaîne. Du coup pas sur que ca soit l'outil adequate ici ;)
Une facon de le faire
var count = 0; for (let i = 0; i < loremIps.split(" ").length; i++) { if(loremArr[i] === "et") { count += 1 } }

console.log("Your text contains " + n + " times the word 'et'.");
