I'm developing a website for fun that adds a random character to a div element on every key press. I have that part working, but what I need is for the program to check if an English word has been created out of the random characters and highlight that word. I've tried many things, and none have worked. Preferably this would highlight it regardless of whether or not there are spaces surrounding the word, but I will be very happy with really any working code.
This is my current JS for random character generation and autoscrolling, also with some code that doesn't work that is meant to search the code.
var letter = 1
var number = 1
const alphabet = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z', '\u0020']
function typingfunction() {
number = Math.floor(Math.random() * 27)
letter = alphabet[number]
document.getElementById("typing").innerHTML = `${document.getElementById("typing").innerHTML}${letter}`
window.scrollTo(0, document.body.scrollHeight * document.body.scrollHeight);
var input = document.getElementById("typing").innerHTML;
var fs = require('fs');
fs.readFile("words_alpha.txt", function(words) {
var words = words.toString().split('\n').filter(function(word) {
return word.length >= 4;
})});
var output = [];
words.forEach(word); {
if (input.match(word)) {
output.push(word);
}
};
console.log(output);
}
window.addEventListener('keydown', typingfunction)
The code for testing a word basically is OK but there was a syntax error in your code (incorrect format for an anonymous function) and also the words array was only declared inside a function but you tried to use it outside the function.
This code slightly reorganises things to take account of this.
I have no way of testing the nodejs filereading (assuming it is nodejs) so if that causes a problem add the tag to your question to get more help in that area.
The code listens for a click on the window and sets the input HTML empty so several trials can be run.

words = allWords.toString().split('\n').filter(function(word) {
return word.length >= 4;
})});

window.addEventListener('click', function () {document.getElementById("typing").innerHTML = '';});
