Break Word Function
I want to write a function where given an index it adds a <br> tag at every Ith index in string. If the index is a space we will insert a <br>, but if it's in the middle of a string we insert -<br>
my_string = "Here's a really really long string that I want to add breaks to at every 20th interval"
insert_break = (str, index) => {
let result = "";
for (let i = 0; i < str.length; i += index) {
let chunk = str.substring(i, i + index);
if (chunk.endsWith(' ')) {
chunk += '<br>';
} else {
chunk += '-<br>';
}
result += chunk;
}
result = result.replace(/-?<br>$/, ''); // remove last `<br>`
return result;
}
renderHtml(insert_break(my_string, 20))
