A step-by-step guide on breaking down words into individual letters using React hooks

I have decided to break down the Text into smaller chunks. Now, my goal is to further divide it into individual letters/characters and then expand this splitting process to include an array within the content.

Take a look at my custom React code:


    import React from "react";
    import "./styles.css";
    import content from "./content";
    
    // Dividing Texts
    const DivideText = React.memo(({ str }) => {
      return (
        <div>
          {str.split(" ").map((item, index) => {
            return <div key={index}>{item}</div>;
          })}
        </div>
      );
    });
    
    // Main Application
    export default function App() {
      return (
        <div className="App">
          <h1>
            <DivideText str={"Lucie Bachman"} />
          </h1>
          <h2>
            <DivideText str={"Hey, I'm sharing my initial post on StackOverflow!"} />
          </h2>
        </div>
      );
    }

Answer №1

When you use the str.split(" ") method, you are essentially instructing the program to split the string based on spaces. This means the string will be divided wherever there is a space present.

However, if you want to split the string into individual characters, you should split it using "" as the separator.

Check out this live demo:

<div>
  {str.split("").map((item, index) => {
    return <div key={index}>{item}</div>;
  })}
</div>

Answer №2

Utilize the split method on a string to extract individual letters

console.log("Hello".split('')); // ['H', 'e', 'l', 'l', 'o']
