A quick overview of the node.js streams interface with basic examples.
This is based on @brycebaril's presentation, Node.js Streams2 Demystified
Streams are a first-class construct in Node.js for handling data.
Think of them as as lazy evaluation applied to data.
These rules are adopted from the AngularJS commit conventions.
var a = ["sdfdf", "http://oooooolol"], | |
handleNetErr = function(e) { return e }; | |
Promise.all(fetch('sdfdsf').catch(handleNetErr), fetch('http://invalidurl').catch(handleNetErr)) | |
.then(function(sdf, invalid) { | |
console.log(sdf, invalid) // [Response, TypeError] | |
}) | |
.catch(function(err) { | |
console.log(err); | |
}) |
Because pointers can be ugh
To understand a pointer, let's review "regular" variables first. If you're familiar with a programming language without pointers like JavaScript, this is what you think when you hear "variable".
When declaring a variable by identifier (or name), the variable is synonymous with its value.
