Example
Basic

Using with document.querySelectorAll
It can be very handy when used with document.querySelectorAll:
Try in REPL%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3A%3Amap(node%20%3D%3E%20node.href)%0A%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%20%3A%3Afilter(href%20%3D%3E%20href.substring(0%2C%205)%20%3D%3D%3D%20'https')%3B%0A%0Aconsole.log(sslUrls)%3B%0A)
document.querySelectorAll returns a NodeList element which is not a plain array, so you normally can't use the map function on it, and have to use it this way: Array.prototype.map.call(document.querySelectorAll(...), node => { ... }). The above code using the :: will work because it is equivalent to:
Auto self binding
When nothing is specified before the :: operator, the function is bound to its object:
