I hope this helps . You can use indexOf() to get the index and use it in the corresponding array.
I have also passed this into the click event so you do not get the error when clicking on the word itself.
code :
var words = ['ab', 'bc', 'cd', 'fe'];
var wordsLetters = ['a-b', 'b-c', 'c-d', 'f-e'];


function getId(element) {
  var word = element.firstElementChild.innerHTML;
  document.getElementById('wordsPlaceholder').innerHTML = word;
  document.getElementById('wordsLettersPlaceholder').innerHTML = wordsLetters[words.indexOf(word)];
}
<ul>
  <li id="w1" onclick="getId(this)"><b>ab</b></li>
  <li id="w2" onclick="getId(this)"><b>bc</b></li>
  <li id="w3" onclick="getId(this)"><b>cd</b></li>
  <li id="w4" onclick="getId(this)"><b>de</b></li>
</ul>
<div style="text-align:center;">
  <b>words: </b><u><b id="wordsPlaceholder"></b></u>
  <div style="display:block;"></div>
  <b>wordsLetters: </b><u><b id="wordsLettersPlaceholder"></b></u>
</div>

wish of those help I'm trying to compare the first character of a string to make sure it isn't equal to any position in an array. Here's the code: , Use a for loop
code :
for(int i = 0; i < array.length; i++){
    if(string.charAt(0) != array[i])
    {
       //Code here
       break;
    }  
}
int i = 0;
while(i < array.length){
    if(string.charAt(0) != array[i])
    {
       //Code here
       break;
    }  
}
boolean checkChar(String string Char[] array){
    return checkCharHelper(string, array, 0);
}

boolean checkCharHelper(String string, Char[] array, int index){
   if(index >= string.length){
      return false;
   }
   if(string.charAt(0) != array[i])
   {
      //Code here
     return true;
   }
   return checkCharHelper(string, array, index + 1);  
}

To fix this issue Hello I am attempting to create a very simplified inventory system and I am having a slight issue. When trying to change an element in my string array, I am instead putting a new string value into the existing array and pushing everything else forwards. , You use the preincrement-operator to fill your array.
code :
inventory[++numbItems] = "Sword";

it should still fix some issue You need to compare using == instead of is. is is actually very seldom useful (except for comparing with built-in constants like None) because it compares if it's the same object ("reference") while == checks for "value equality". So is should only be used to compare with a singleton or you really know what you're doing.
However you could just use a try and except around data.index and it should work without any manual iteration and comparisons:
code :
try:
    print(data.index(inputo))
except ValueError:
    print('not found')
for idx, item in enumerate(data):
    if item == inputo:
        print(idx)
else:
    print("not found")

will be helpful for those in need A naive implementation not using Linq to play around with in unity right away
code :
using System.Collections.Generic;
using UnityEngine;

public class Encryption : MonoBehaviour {

    public string testString = "Every lower case vowel gets replaced by the 'next' one.";

    Dictionary<char, char> charMap;
    string result = "";

    void Start () {

        charMap = new Dictionary<char, char>() {
            {'a','e'},
            {'e','i'},
            {'i','o'},
            {'o','u'},
            {'u','a'}
        };
        result = "";    

        for (int i = 0; i < testString.Length; i++) {

            result += charMap.ContainsKey(testString[i]) ? charMap[testString[i]] : testString[i];
        }

        Debug.Log(result);
    }

}

this will help You need to catch onchange event of your input box. I hope you have an input with its ID or class. with jQuery you can do this like
code :
$("#buttonId").on("click", function(){

   userInput = $("#userWord").val();
   requestAndcheckIf(userInput);
})
requestAndcheckIf: function (userInput) {

        const request = new XMLHttpRequest();

        // Open a new connection, using the GET request on the URL endpoint
        request.open('GET', 'https://ghibliapi.herokuapp.com/films', true);

        request.onload = function () {
            // Begin accessing JSON data here
            const data = JSON.parse(this.response);

            data.forEach((movie, index) => {
                // Log each movie's title
                console.log(movie.title);

                if (movie.title.includes(userInput)) {
                    alert("Gotcha! It is present in the " + index)
                } else {

                }
            });
        }
        request.send();
}
