<p>All filters and tags in <a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/Shopify/liquid">shopify/liquid</a> are supposed to be built in LiquidJS, but not those business-logic specific tags/filters which are typically from Shopify themes (see <a href="./plugins.html#Plugin-List">Plugins List</a> in case youre looking for them and feel free to add yours to the list). Though being compatible the Ruby version is one of our priorities, there are still some differences:</p>
<ul>
<li>Truthy and Falsy. All values except <code>undefined</code>, <code>null</code>, <code>false</code> are truthy, whereas in Ruby Liquid all except <code>nil</code> and <code>false</code> are truthy. See <a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/harttle/liquidjs/pull/26">#26</a>.</li>
<li>Number. In JavaScript we cannot distinguish or convert between <code>float</code> and <code>integer</code>, see <a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/harttle/liquidjs/issues/59">#59</a>. And when applied <code>size</code> filter, numbers always return 0, which is 8 for integer in ruby, cause they do not have a <code>length</code> property.</li>
<li><a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/Shopify/liquid/wiki/Introduction-to-Drops">.to_liquid()</a> is replaced by <code>.toLiquid()</code></li>
<li><a target="_blank" rel="noopener external nofollow noreferrer" href="https://www.rubydoc.info/gems/liquid/Liquid/Drop">.to_s()</a> is replaced by JavaScript <code>.toString()</code></li>
<li>Iteration order for objects. The iteration order of JavaScript objects, and thus LiquidJS objects, is a combination of the insertion order for string keys, and ascending order for number-like keys, while the iteration order of Ruby Hash is simply the insertion order.</li>
<li>Sort stability. The <a href="https://liquidjs.com/filters/sort.html">sort</a> stability is also not defined in both shopify/liquid and LiquidJS, but its <a target="_blank" rel="noopener external nofollow noreferrer" href="https://v8.dev/features/stable-sort">considered stable</a> for LiquidJS in Node.js 12+ and Google Chrome 70+.</li>
<li>Trailing unmatched characters inside filters are allowed in shopify/liquid but not in LiquidJS. It means filter arguments without a colon like <code>{{ "a b" | split " "}}</code> will throw an error in LiquidJS. This is intended to improve Liquid usability, see <a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/harttle/liquidjs/issues/208">#208</a> and <a target="_blank" rel="noopener external nofollow noreferrer" href="https://github.com/harttle/liquidjs/issues/212">#212</a>.</li>
