cljs

Functions for working with JavaScript that mirror Clojure behaviour.

apply clj/s≠

clj

(apply obj k args)

cljs

(apply obj k arg-array)

assoc! clj/s≠

(assoc! obj & pairs)

cljs

Sets key-value pairs on obj, returns obj.

assoc-in! clj/s≠

clj

(assoc-in! obj ks v)

cljs

(assoc-in! obj [k & ks] v)

Mutates the value in a nested object structure, where ks is a sequence of keys and v is the new value. If any levels do not exist, objects will be created.

assoc-in* cljs

(assoc-in* obj [k* & ks*] v)

call clj/s

(call obj k & args)

contains? cljs

(contains? obj k)

contains?* clj/s≠

clj

cljs

(contains?* obj k*)

empty-obj clj

get clj/s≠

(get obj k)

(get obj k not-found)

cljs

Returns the value mapped to key, not-found or nil if key not present.

get-in clj/s≠

(get-in obj ks)

(get-in obj ks not-found)

cljs

Returns the value in a nested object structure, where ks is a sequence of keys. Returns nil if the key is not present, or the not-found value if supplied.

get-in* cljs

(get-in* obj ks*)

(get-in* obj ks* not-found)

JSLookup cljs

lookup cljs

(lookup obj)

Returns object which implements ILookup and reads keys from obj.

lookup-sentinel clj/s

obj clj/s≠

(obj & keyvals)

cljs

Create JavaSript object from an even number arguments representing interleaved keys and values. Dot-prefixed symbol keys will be renamable.

push! clj/s

(push! a v)

reflect-property clj

select-keys clj/s≠

(select-keys obj ks)

cljs

Returns an object containing only those entries in o whose key is in ks

select-keys* cljs

(select-keys* obj ks*)

Returns an object containing only those entries in o whose key is in ks

unchecked-get clj/s

(unchecked-get obj k)

unchecked-set clj/s≠

clj

(unchecked-set obj & pairs)

cljs

(unchecked-set obj k val)

unshift! clj/s

(unshift! a v)

update! clj/s≠

(update! obj k f & args)

cljs

'Updates' a value in a JavaScript object, where k is a key and f is a function that will take the old value and any supplied args and return the new value, which replaces the old value. If the key does not exist, nil is passed as the old value.

update-in! clj/s≠

(update-in! obj ks f & args)

cljs

'Updates' a value in a nested object structure, where ks is a sequence of keys and f is a function that will take the old value and any supplied args and return the new value, mutating the nested structure. If any levels do not exist, objects will be created.

update-in* cljs

(update-in* obj ks* f args)

wrap-key clj/s≠

clj

(wrap-key k)

(wrap-key k obj)

Convert key to string at compile time when possible.

cljs

(wrap-key k)

Returns k or, if it is a keyword, its name.

wrap-keys clj

(wrap-keys ks)

Fallback to wrapping keys at runtime
