i want to find any english word (min 4 letters) in one string.
Eg: hello123fdwelcome => ["hello", "welcome"];
Could you suggest for me any solution or javascript lib to match english word.
Thanks
You can use this list of words https://github.com/dwyl/english-words
var input = "hello123fdwelcome";
var fs = require('fs');
fs.readFile("words.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);
});

I have only one number like "100000"
I wan't to split this number same as [20000,20000,20000,20000,20000] in array
so if number is 138000 then it should be like [20000,20000,20000,20000,20000,20000,18000]
How to do this?
let num = 118000,
num_array = [];
while (num > 0) {
if (num >= 20000) {
num_array.push(20000);
num -= 20000;
} else {
num_array.push(num);
break;
}
}
console.log(num_array);
I think this is what you want, please post what you tried, so that it helps to understand where you failed.

I am trying to split the content of an article into its sentences.
For example, Splitting
"Hi, My Name is Mark. I am going to the store, Do you need anything?"
to an array like
["Hi," , "My Name is Mark." , "I am going to the store," , "Do you need anything?"]
Could you help with the code using split() ?
let str = "Hi, My Name is Mark. I am going to the store, Do you need anything?",
strArray = str.split(/[,.]/),
spliterArray = str.match(/[,.]/g),
newArray = [];
for (let [key, val] of strArray.entries()) {
let splitVal = spliterArray[key] ? spliterArray[key] : "";
newArray.push(val.trim() + splitVal);
}
console.log(newArray);

my question is probably simple for most but its troubling me and ive been googling for sometime now.
I dont want allow copy or paste content and emoji characters in input fields.
var checkTf = function() {
let charcode_max = 255;
let tf = document.getElementById("tf");
for (let i = tf.value.length - 1; i >= 0; i--) {
if (tf.value[i].charCodeAt(0) > charcode_max) {
tf.value = tf.value.substr(0, i) + tf.value.substr(i + 1);
}
}
}
<html>
<head></head>
<body>
<textarea id="tf" oninput="checkTf()"></textarea>
</body>
</html>
You may increase charcode_max.

Var randomLetters = "ljhgfdza";
Var randomString = "";
Now I'll have to add elements in the first variable to the second Randomly
Using the while loop, and Math.floor(Math.random() * random letters.length)
I am having a problem at my
"While (condition)" what should it be?
To flat out answer your question, you can use:
while(randomLetters.length > 0){
Then when you use a letter from randomLetters, you delete the letter and the length is now 1 less.
This will be enough for you:
const randomLetters = "ljhgfdza";
const returnRandom = (randomString) => {
const arrString = [...randomString].sort((a, b) =>{
return 0.5 - Math.random()
}).join("");
console.log(typeof arrString,arrString);
}
returnRandom(randomLetters);
but... in this case sort method is not that random as you think. This link will tell you why. I would do this with reduce() or map(), both are described in link above.

I need to find an element that's text value is 0.
I do:
var d = $('.content').find('div');
if(d.text().length === 0){
//do something
}
Is there a way to put the above logic in the selector?
I've tried:
var d = $('.content').find('div:empty');
But no luck as the div may have other empty html tags in.
Use a filter
var elems = $('.content').find('div').filter(function() { return $(this).text() == 0 });
