How to split a string into array without using Array.split?

Question

Is it possible to implement Array.split() just by using loops without using any built in functions?

I want this: "Hello how are you" ---> ["Hello" , "how", "are", "you"] without using Array.split() or any built in function.

• distro: Of course it's possible. What have you tried so far? How would you approach the problem?
• Mr. Innovator: You can use the String.indexOf(), make an array the do a while loop, you can search for the documentation

Answer 1

try this

let str= "Hello how are you";
 
let array = [''];
let j = 0;
for (let i = 0; i < str.length; i++) {
 if (str.charAt(i) == " ") {
 j++;
 array.push('');
 } else {
 array[j] += str.charAt(i);
 }
}
console.log(array)

• Mohammad Ali Rony: if answered useful mark as answers
• Chris P: If string start with ' ' (empty char) the first element of the array will be empty so do for the last char. So maybe a str.strip() (if there is in javascript may be used depends of the need).

let word = "stack over flow murat";
let arr = []
let tempWord= ""
for (let i = 0; i<word.length; i++){
if(word[i]===" "){
 arr.push(tempWord);
 tempWord="";
}
else{
 tempWord+=word[i];
 }
}
arr.push(tempWord);
console.log(arr);
