How Can I Retrieve Substrings Enclosed in Backticks Using JavaScript?

I’m looking for a method in JavaScript that extracts parts of a long string that are surrounded by backticks. For example, imagine a paragraph that contains fragments like alpha and bravo embedded within. How can I efficiently pull out these specific segments?

Below is an alternative code example to illustrate the concept:

function findQuotedParts(textInput) {
  const regex = /`([^`]+)`/g;
  let result = [];
  let capture;
  while ((capture = regex.exec(textInput)) !== null) {
    result.push(capture[1]);
  }
  return result;
}

const sampleText = "In old legends, `mystery` surrounds every `heroic deed` performed.";
console.log(findQuotedParts(sampleText));

hey, try using matchAll; it returns an iterator of caputred segements you can spread into an arr. works neate but keep an eye on polyfils for older browers.

Working on a project for interactive documentation, I had to extract pieces of text between backticks and decided to rely on a regular expression. I used a similar loop approach to capture each occurrence, making sure to handle multiple matches carefully. In practice, this method proved reliable when dealing with both short and long strings. However, I made sure to validate the input first to avoid unbalanced backticks which can lead to skipped sections. This technique, while simple, turned out to be an effective and efficient solution in most scenarios.

A different method I’ve used involves taking advantage of the String.prototype.match method along with a carefully crafted regex. In one of my projects, the regex approach using match combined with Array.from allowed for concise code when handling well-formed inputs. It was essential to consider cases where inputs might have missing or extra backticks. This required adding some conditional checks post-extraction to ensure data integrity. Although the regex-based approach is efficient in many scenarios, profiling for performance on larger texts confirmed that simple patterns perform reliably without significant overhead.

yo, you can also split the string by the backticks and grab the odd indexes. works good if you guarantee matching pairs though. gives a neat non-regex alternative if u wanna avoid pattern issues in messy texts

In my experience working with dynamic string data, I found that combining indexOf and substring methods can offer a robust solution without relying solely on regular expressions. By iterating through the string and manually tracking the positions of opening and closing backticks, you can gracefully handle cases with uneven or missing delimiters. This approach not only provides more controlled error handling but also lets you optimize for performance when processing very large text blocks. Personally, this method has proven to be both flexible and reliable in several projects.
