Questions & Answers

As answered by people managing Learn JavaScript and ShareScan.io.

What makes your product unique?

ShareScan.io's answer:

ShareScan continuously monitors your entire website for broken social previews, Open Graph issues, and metadata problems โ€” then alerts your team in Slack before those issues hurt clicks, campaigns, or trust. Unlike one-off preview checkers, ShareScan is built for ongoing monitoring across many pages, so problems donโ€™t go unnoticed after content changes, releases, or deployments.

Why should a person choose your product over its competitors?

ShareScan.io's answer:

ShareScan is built for teams that want to move from manual checking to continuous monitoring. Instead of validating one URL at a time, ShareScan helps you keep track of preview issues across your website and notifies you when something breaks.

  • Monitors your whole site, not just a single page

  • Alerts you in Slack when issues are detected

  • Helps prevent lost clicks and broken campaigns

  • Useful for marketers, SEO teams, and developers

  • Makes social preview QA part of your workflow, not an afterthought

If link previews matter to your traffic, brand consistency, or campaign performance, ShareScan gives you a faster and more reliable way to catch issues early.

How would you describe the primary audience of your product?

ShareScan.io's answer:

ShareScan.io is built for marketing teams, SEO specialists, content teams, and developers who manage websites where social sharing, metadata quality, and link preview consistency matter. It is especially useful for teams that publish frequently, run campaigns, or manage larger sites where preview issues can easily slip through unnoticed.

What's the story behind your product?

ShareScan.io's answer:

ShareScan was created to solve a frustrating but easy-to-miss problem: pages can look perfectly fine on-site while still breaking when shared on social platforms, messaging apps, or collaboration tools. Missing Open Graph tags, broken images, stale metadata, and invalid cards can quietly hurt traffic, engagement, and trust.

We built ShareScan to help teams catch those issues before users do. Instead of relying on manual spot checks, ShareScan continuously monitors websites for preview problems and sends alerts when something breaks.

Which are the primary technologies used for building your product?

ShareScan.io's answer:

ShareScan.io is built using modern web technologies for crawling, monitoring, analysis, and team notifications. The platform combines website scanning, metadata validation, backend processing, and Slack integrations to help teams detect and respond to broken preview issues quickly.

Who are some of the biggest customers of your product?

ShareScan.io's answer:

We are not publicly listing customer names at this time.

    I haven't done this course, but I have been programming with Javascript for about ~1.5years and can build things with React, the best course I found, and I bet it would translate to angular, is learnjavascript.online. Another resource that is good is http://csbin.io/ which is a codesmith platform. The former is more practical and will teach you prequisite concepts to use frameworks, the latter is more theoretical... Source: about 3 years ago
  • Current self taught developers who started of with no knowledge and then used a large free course online. How much of your knowledge came from said course
    The Jad Joubran courses on the other hand really upped my skill level and helped me make the jump from passive learning, exercises and very small projects to making legitimate web apps. That was probably the biggest/scariest jump I've made in my learning journey, and without those courses and the hands-on skill checks and projects he makes you do, I wouldn't have gotten to where I am (which is close to finishing...

  • What do you think about interactive courses like Scrimba? Are there any that you like or would recommend?
    Hi everyone! I'm in the very early stages of creating an interactive course and I would like to hear your thoughts on them. So far I've come across Scrimba and Jad Joubran's learn X series of sites (learnjavascript.online, learnhtmlcss.online, etc...). Has anyone completed any of them? Any there any others that you really like or would recommend? Source: about 3 years ago
  • No prior coding experience, what should I be doing and what to look for in a bootcamp?
    Learnprogramming.online and learnjavascript.online (I haven't really looked at these too deeply yet, but someone just shared them with me and they look really cool!). Source: about 3 years ago
  • What is something you learned while learning javascript that you wish you had known from the start?
    I am learning to code in Javascript using https://learnjavascript.online/ but am finding it a lonely experience. Hoping to jump in and learn with others as I go. Hope this question may help get things going. Source: about 3 years ago
