import { lodash } from "https://dotland.deno.dev/x/lodash_es@v0.0.2/src/seq.js";
Creates a lodash
object which wraps value
to enable implicit method
chain sequences. Methods that operate on and return arrays, collections,
and functions can be chained together. Methods that retrieve a single value
or may return a primitive value will automatically end the chain sequence
and return the unwrapped value. Otherwise, the value must be unwrapped
with _#value
.
Explicit chain sequences, which must be unwrapped with _#value
, may be
enabled using _.chain
.
The execution of chained methods is lazy, that is, it's deferred until
_#value
is implicitly or explicitly called.
Lazy evaluation allows several methods to support shortcut fusion. Shortcut fusion is an optimization to merge iteratee calls; this avoids the creation of intermediate arrays and can greatly reduce the number of iteratee executions. Sections of a chain sequence qualify for shortcut fusion if the section is applied to an array and iteratees accept only one argument. The heuristic for whether a section qualifies for shortcut fusion is subject to change.
Chaining is supported in custom builds as long as the _#value
method is
directly or indirectly included in the build.
In addition to lodash methods, wrappers have Array
and String
methods.
The wrapper Array
methods are:
concat
, join
, pop
, push
, shift
, sort
, splice
, and unshift
The wrapper String
methods are:
replace
and split
