|
| 28 | <p><a href="http://underscorejs.org/">Underscore</a> is a library of utility functions. <a href="https://lodash.com/">Lodash</a> is a more modern implementation of it.</p>
|
| 29 | <p>Unlike Lodash and Underscore, scour is primarily a utility to traverse deep object trees. Lodash covers many functions useful for managing objects and arrays, but very few for making immutable edits.</p>
|
| 30 | <p>Scour can also traverse through scopes using <a href="index.html#go">go()</a>, which allows you to manage a subtrees and navigate through it.</p>
|
| 31 | <p>Scour also has extensions via <a href="index.html#use">use()</a>, which allows you to navigate your data with model-like objects (<a href="extensions_example.html">example</a>).</p>
|
| 32 | <ul>
|
| 33 | <li>Features
|
| 34 | <ul>
|
| 35 | <li><strong>Lodash</strong>: includes object utilities, as well as functions, strings, and many others.</li>
|
| 36 | <li><strong>Scour</strong>: only utilities relevant for objects/arrays.</li>
|
| 37 | </ul>
|
| 38 | </li>
|
| 39 | <li>Chaining
|
| 40 | <ul>
|
| 41 | <li><strong>Lodash</strong>: supports chaining.</li>
|
| 42 | <li><strong>Scour</strong>: supports chaining, and scope traversal (<a href="index.html#go">go()</a>).</li>
|
| 43 | </ul>
|
| 44 | </li>
|
| 45 | <li>Immutable utilities
|
| 46 | <ul>
|
| 47 | <li><strong>Lodash</strong>: has a lot, but none for setting keys deep in an object tree.</li>
|
| 48 | <li><strong>Scour</strong>: has <a href="index.html#get">get()</a>.</li>
|
| 49 | </ul>
|
| 50 | </li>
|
| 51 | <li>Lazy evaluation
|
| 52 | <ul>
|
| 53 | <li><strong>Underscore</strong>: not supported.</li>
|
| 54 | <li><strong>Lodash</strong>: calls to <code>.map()</code>, <code>.filter()</code> (et al) can be chained and will be optimized.</li>
|
| 55 | <li><strong>Scour</strong>: not supported yet.</li>
|
| 56 | </ul>
|
| 57 | </li>
|
| 58 | <li>Size (minified and gzipped)
|
| 59 | <ul>
|
| 60 | <li><strong>Underscore</strong>: 5.7kb (as of 1.8.3)</li>
|
| 61 | <li><strong>Lodash</strong>: 18.4kb (as of 3.0.0)</li>
|
| 62 | <li><strong>Scour</strong>: 3.4kb</li>
|
| 63 | </ul>
|

|
| 66 | <h2 id="versus-immutable.js">Versus Immutable.js</h2>
|
| 67 | <p><a href="http://facebook.github.io/immutable-js/">Immutable</a> is a library for dealing with data in an immutable fashion.</p>
|
| 68 | <p>Scour also has extensions via <a href="index.html#use">use()</a>, which allows you to navigate your data with model-like objects (<a href="extensions_example.html">example</a>).</p>
|
| 69 | <p>It is really hefty (like 57kb) and has a huge API surface area.</p>
