I have a Sentence and also an array of clickable words from the sentence. The Array does not include the punctuation marks.
Here is a sentence
Into the trunk we put two poles and the can of worms and a sack of sandwiches and a thermos of water. “We’re going on a journey,” my father said. “To a secret place. We’ll catch the air! We’ll catch the breeze!”
Here is the structure of the clickable words. It's an array containing the indexes of where within the sentence the word begins and ends. This Array does not contain the punctuation marks in the sentence
Theu punctuation marks are not clickable.

Here is my code that gets the clickable words
const getWordsFromTokens = tokens.reduce((words, token)=>{
let start = token.position[0]; //Start is the first character of the token value in the sentence
let end = token.position[1]; // end is the last character of the token value in the sentence
let diffrenceBetweenLastPositionAndFirst = end (end-start);
/* You get punctuationMarks or any characters not in the Tokens by getting the string between
the end and diffrence between the end and start
*/
let punctuationMarks = content.substring(end, (diffrenceBetweenLastPositionAndFirst));
console.log(punctuationMarks);
words.push( content.substring(start, end) punctuationMarks); //concat with any space of pucntuation mark after the word.
return words; //<- return this to be used in next round of reduce untill all words are
},[]);
Here is How I'm rendering the text
return (
<div>
<p> {
getWordsFromTokens.map((word, index)=>{
return <a href={'/word/' word} > {word}</a>
})
}
</p>
</div>
)
Here is my problem, When I render the text, it does not look exactly like the original text. What is it that I could be doing wrong?
Here is how the final Result looks like
Into the the tr trunk we p we p put tw two po poles and and th the ca can of of w worms and and a a sack of of s sandwiches and a the and a a thermos of wat of w water. “We We’re goin going on a on a a journey,” my f my f father said. said. “T To a a secret place place.

What about a solution like this? I use a cursor to track the position inside the sentence.

I think that using RegExp would make your life easier:
const content = `Into the trunk we put two poles and the can of worms and a sack of sandwiches and a thermos of water. "We're going on a journey," my father said. "To a secret place. We'll catch the air! We'll catch the breeze!`;
const result = content.match(/([\w']) |([\.;,:-_?!"] [\s"]*["]*)/gim);
console.log(result);
const punctuation = /[\.;,:\-_?!"] /;
function App() {
return (
<div>
{result.map((w) =>
punctuation.test(w) ? w : <a href={`/word/${w}`}>{w '\n'}</a>
)}
</div>
);
}
ReactDOM.render(<App/>, document.getElementById("root"))<div id="root"></div>
