I'm trying to read data from a JSON file that contains a list of blogs. I want to break each of those blogs into small paragraphs. I thought adding \n would do the job but it's not. How can I achieve this?

This is my blogs.json file:

This clued me in to the goal of this book, to escape what has been perpetuated our entire lives. However, I was still skeptical.

Sure, someone like Tim Ferriss, Princeton graduate and energy-supplement extraordinaire could pull it off, but that doesn't mean that me, the average Joe, could somehow make an automated stream of revenue so that I can live all around the world and have no worries.The next chapter, E is for Elimination, had the most profound effect on me. It presented ideas such as Parkinson's Law (work expands to fill the time allotted to it) and the Pareto Principle (80/20), ideas I had heard from videos before, but never explained as well as in this chapter. After reading, I immediately evaluated my time wasters and consumers and began to slowly deconstruct my day and how to best optimize it. This chapter was one that I could apply the day after reading it successfully, so it was very useful. \n The next chapter, E is for Elimination, had the most profound effect on me.

And here's how I'm reading from it BookDetails.js :

import React, { useEffect, useState } from "react";
import { useParams } from "react-router-dom";

const BookDetails = () => {
  const { id } = useParams();
  const [blog, setBlog] = useState({});

  useEffect(() => {
    const url = `/blogs.json`;
    console.log(url);
    fetch(url)
      .then((res) => res.json())
      .then((data) => {
        const currentBlogArray = data.filter((book) => book.id == id);
        setBlog(currentBlogArray.length > 0 ? currentBlogArray[0] : {});
      });
  }, []);

  return (
    <div className="px-6">
      <h2>This is book details: {id} </h2>

      <h2 className="flex justify-center font-bold text-2xl mb-6">
        {" "}
        {blog.name}
      </h2>
      <h2> {blog.blog}</h2>
    </div>

You can add <p> tag for each needed place on the string then while reading JSON split it based on <p> tag and then create your own HTML.

example:

const json = "Paragraph 1<p>Paragraph 2";
const p = document.querySelector('#paragraph');

p.innerHTML = json.split('<p>').map(paragraph=>{
       return '<p>' + paragraph + '</p>';
      }).join('')
<html>
<body>
<div id="paragraph"> </div>
</body>
</html>

import React, { useEffect, useState } from "react";
import { useParams } from "react-router-dom";

const BookDetails = () => {
  const { id } = useParams();
  const [blog, setBlog] = useState({});
  useEffect(() => {
    const url = `blogs.json`;
    fetch(url)
      .then((res) => res.json())
      .then((data) => {
        const currentBlogArray = data.filter((book) => book.id == id);
        const currentBlog =
          currentBlogArray.length > 0 ? currentBlogArray[0] : {};
        setBlog({
          ...currentBlog,
          blog: currentBlog.blog.split("\n"),
        });
      });
  }, []);

  return (
    <div className="px-6">
      <h2>This is book details: {id} </h2>
      <h2 className="flex justify-center font-bold text-2xl mb-6">
        {blog.name}
      </h2>
      <h2>
        {blog.blog?.map((paragraph) => {
          return (
            <p>
              <span style={{ marginLeft: 25 }}></span>
              {paragraph}
            </p>
          );
        })}
      </h2>
    </div>
  );
};

export default BookDetails;

Thanks. I edited my post to add some more detail. How can i apply the changes that you suggested in my BookDetails.js?
I have already updated it, the logic is the same.
this is perfect! Thanks so much! If I want to add some more space so like a double line break, how can I achieve this?
There are several ways to do that one of them like using margin, I have updated. If this answer is okay, accept it.
i just did javascript <h2> {blog.blog?.map((paragraph) => { return <p className="mb-4">{paragraph}</p>; })} </h2> and voila! Thanks a lot for the help again

Replace:

<h2> {blog.blog} </h2>

With

<h2> {blog.blog.split(/\n/).map((t,i) => (<div key={i}>{t}</div>))} </h2>

This will split your text at the newline character (discarding it). Each resulting substring is then mapped into a div for display.

Replace \\n\\ with \n to add a line break. Use \n\n to add two line breaks.
