footnote1Underscore’s un:flatten() defaults to depth of Infinity while LoDash’s lo:flatten() and ES’s flat() proposal (and NoDash’s flat()) – to depth of 1.

footnote2NoDash’s template() syntax is not based on <%ERB%> but on {{Mustache.js}}.

footnote3sq:Sqimitive\Core::masker() provides a similar functionality.

footnote4sq:Sqimitive\Ordered::indexFor() provides a similar functionality.

footnote5Exists in Underscore.String: https://github.com/epeli/underscore.string/

footnote6Not supported natively in any version of Internet Explorer.

footnote7sq:Sqimitive\Core::unique() provides a similar functionality (but doesn’t prepend prefix to the result).

footnote8NoDash’s invoke() and Underscore’s un:invoke() call a method on every object in an array parameter while LoDash’s lo:invoke() accepts a single object and calls a method on it.

footnote9sq:Sqimitive\Core::stub() is the same.

footnote10Underscore’s un:mixin() extends Underscore’s own functionality. LoDash’s lo:mixIn() is similar to sq:Sqimitive\Core::mixIn().

footnote11Use instanceof to check for these types. For example: /0.*/ instanceof RegExp.

footnote12Underscore’s un:isEqual() and LoDash’s lo:isEqual() are very elaborate. NoDash simply defers to == so in NoDash _.isEqual([], []) === false.

footnote13sq:Sqimitive\Core::deepClone() provides a similar functionality.

footnote14NoDash’s ajax() semantics is very similar to jQuery’s ajax().

footnote15sq:Sqimitive\Core::picker() provides a similar functionality.

footnote16NoDash’s once() can be used like un:memoize()/lo:memoize() with dumb hashFunction/resolver, returning the same cached value regardless of arguments.

footnote17LoDash’s lo:at() supports complex string path notation (a[0].b.c).

footnote18LoDash’s lo:property() supports complex string path notation (a[0].b.c) while in NoDash’s property() and Underscore’s un:property() a string stands for a single key.

footnote19LoDash’s lo:flip() is very different: it wraps a function, inverting its argument order.

footnote20Do not confuse escape() with the native o:escape() function used for URL encoding.

footnote21Underscore’s un:object() combines NoDash’s object() (takes two lists: keys and values) and fromEntries() (takes one list: key-value pairs).
