Learn JavaScript
Apollo.ioWe use Apollo with our Sales and BDR team to manage our cold outreach. The strength of the platform is the sequences and cadences that you can set up. Compared to other tools we have used in the past like Salesloft the UI is much easier to navigate. The main limitation is that the quality of data isn't as vast and often I can find prospects on Linkedin but not in Apollo.
Apollo.io might be a bit more popular than Learn JavaScript. We know about 69 links to it since March 2021 and only 48 links to Learn JavaScript. We are tracking product recommendations and mentions on various public social media platforms and blogs. They can help you identify which product is more popular and what people think of it.
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
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...

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
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
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
Personal email domains destroy this. Clearbit's Enrichment API returns a null company when it hits gmail.com. Apollo routes personal domains straight to a consumer bucket and skips B2B fields entirely. Even PDL's /person/enrich endpoint โ the most permissive of the major providers โ gives you around 32% hit rate on Gmail addresses versus 74% on corporate domains. I measured this across 6,200 signups for a... - Source: dev.to / 2 months ago
A few things worth flagging: PDL beats Clearbit's historical rates for US and Western European companies, but drops to ~52% match rate for Japan and South Korea specifically. Apollo underperforms on raw company matching but returns significantly more contacts per domain in Prospector-style queries than Clearbit's Prospector ever did โ the tradeoff is more stale titles in the result set. Hunter.io is fast and cheap... - Source: dev.to / 2 months ago
One thing comparison guides consistently get wrong: Clay is not an enrichment API. It's a waterfall orchestration tool that calls People Data Labs, Apollo, Clearbit, and others in sequence for you. It's useful, but it adds 2โ8 seconds of latency per row in my runs and costs more per match than going direct. For a CRM webhook flow where you need sub-second enrichment calls, Clay is the wrong layer to hit first. - Source: dev.to / 3 months ago
Last year I ran the same LinkedIn Sales Navigator export through three enrichment APIs. Apollo matched 61% of the emails. Hunter.io matched 54%. An OSINT-first pipeline I'd built in n8n โ pulling from public sources before hitting any paid API โ matched 79% and cost roughly $0.003 per contact. The delta wasn't magic. It was sequence. - Source: dev.to / 3 months ago
Despite having its LinkedIn Page removed in 2025, Apollo remains a functional enrichment and outreach platform with 275M+ contacts. The free tier includes 10,000 credits and the $49/month basic plan is the cheapest entry point for a combined enrichment-plus-sequencing workflow. Apollo's data collection methods have attracted LinkedIn's attention, but the product continues to operate. The risk I'd assign it:... - Source: dev.to / 3 months ago
