Github.com ui .currently does not natively supoport search for multiple topic tags as of now. However their api allows you to query multiple tags. Below is a simple example to query github.com with ecs and go topic tags.

curl -H "Accept: application/vnd.github.mercy-preview+json" \
https://api.github.com/search/repositories?q=topic:ecs+topic:go

Response from the github can be rather verbose so lets filter only relavant info such repo url and description.

curl -H "Accept: application/vnd.github.mercy-preview+json" \
https://api.github.com/search/repositories\?q\=topic:ecs+topic:go | jq '.items[] | {url:.url, description:.description}'

JavaScript Interview Questions

Q1: Explain equality in JavaScript ☆

Answer: JavaScript has both strict and type–converting comparisons:

• Strict comparison (e.g., ===) checks for value equality without allowing coercion
• Abstract comparison (e.g. ==) checks for value equality with coercion allowed

1. Write poly-fill of Object.create and explain why it worked:

if(typeof Object.create != "function") {
    Object.create = function(param) {
        var Fun = function(){};
        Fun.prototype = param;
        return new Fun();
    }
}

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.
