  :js-object -> :object
:js-promise -> :promise
:js-iterable -> :iterable
:java.lang.Class -> :class

• Added :iterable to :all-tags entry of lasertag.core/tag-map return value, for all java values that are instances of java.lang.Iterable
  

0.10.1

2025-03-12

Fixed

• Length of java primitive array using alength

0.10.0

2024-11-24

Breaking changes

• Changed the following tags (result of calling lasertag.core/tag):
  :js/Set -> :set
:js/Map -> :map
:js/WeakSet -> :set
:js/WeakMap -> :map
:js/Array -> :array
:js/ArrayBuffer -> :byte-array

• Changed all tags that were namespaced with js/ to use a unified kebab-case convention, e.g.:
  js/Object -> :js-object
js/Int8Array -> :js-int8-array

• All typed arrays in JS now get tagged with :array, with a more granular tag e.g. :js-int8-array in the :all-tags entry of return value from lasertag.core/tag-map

## 0.7.0
2024-11-3
### Added
- The following new entries in the return value of `lasertag.core/tag-map`:<br>
  - `:set-like?`
  - `:java-util-class?`
  - `:java-lang-class?`
  - `:classname`

### Breaking changes
- Some instances of java classes are now given tags like `:set`, `:map`, `:seq`,
or `:array`.
  Examples:
```Clojure
  (tag (java.util.HashMap. {"a" 1 "b" 2}))   ; => :map
  (tag (java.util.HashSet. {"a" "b" "c"}))   ; => :set
  (tag (java.util.ArrayList. [1 2 3]))       ; => :array

0.6.0

2024-10-16

Added

• If tag of coll is :seq, and coll is a list such as clojure.lang.PersistentList, then :list is added to the :all-tags entry in the return value from tag-map.

• If coll is an array-map, :array-map is added to the :all-tags entry in the return value from tag-map:

(tag-map (array-map {"one" 1 "two" 2 "three" 3}))
=>
{:tag           :map
 :type          clojure.lang/PersistentArrayMap[]
 :carries-meta? true
 :all-tags      #{:coll :array-map :map}
 :coll-type?    true
 :map-like?     true
 :number-type?  false
 :coll-size     9}

0.5.1
