Let's explore a few ways to do immutable updates in js. We'll start with this data:

var data = {
  foo: {
    bar: 1,
    baz: 2,
  }
};

function providesTimer(Component) {
  return class Timer extends React.Component {
    constructor(props) {
      super(props);
      this.timers = [];
      this.setTimeout = this.setTimeout.bind(this);
    }
    
    
    setTimeout(callback, ms) {

updateIfChanged is a pattern that allows preventing updates based on a unique key. It inverts control of updates from a dumb child to the smarter parent. It's particularly useful because it can avoid the normal issue of children and callbacks causing a rerender when it's not truly required.

The alternative workaround is usually memoizing the children and callbacks which can be expensive, complicated, and leak memory.

Implementation

import deepEqual from 'lodash/isEqual';

var mongoose = require('mongoose');
var kittySchema = exports.schema = mongoose.Schema({

var Kitten = exports.model = mongoose.model('Kitten', kittySchema);

UU basics

UU supports many basic commands. Here are some. Writing UU scripts requires some knowledge but reading and modifying them should be easy for people familiar with english and one or more programming languages.

uu with "$path" split-on / get -1
echo foo 1 bar 2 baz | uu with-stdin spit-on ' ' match '\w+' print %s
echo '{"key": "value"}' | uu with-stdin json-get 'key' print %s
echo '{"key": "value"}' | uu with-stdin json-set 'key' 'value2' print %j
