applyclj/s≠
(apply obj k args)(apply obj k arg-array)Apply function k of obj, which is bound as this.
(j/apply o :someFunction #js [arg1 arg2])
Apply function `k` of `obj`, which is bound as `this`. ``` (j/apply o :someFunction #js [arg1 arg2]) ```
assoc!clj/s≠
(assoc! obj & keyvals)(assoc! obj & pairs)Sets key-value pairs on obj, returns obj.
(j/assoc! o :foo 10)
(j/assoc! o .-foo 10)
Sets key-value pairs on `obj`, returns `obj`. ``` (j/assoc! o :foo 10) (j/assoc! o .-foo 10) ```
assoc-in!clj/s≠
(assoc-in! obj ks v)(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.
(j/assoc-in! o [:foo :goo] 10)
(j/assoc-in! o [.-foo .-goo] 10)
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. ``` (j/assoc-in! o [:foo :goo] 10) (j/assoc-in! o [.-foo .-goo] 10) ```
callclj/s≠
(call obj k & args)Call function k of obj, which is bound as this.
(j/call o :someFunction arg1 arg2)
Call function `k` of `obj`, which is bound as `this`. ``` (j/call o :someFunction arg1 arg2) ```
contains?clj/s≠
(contains? obj k)Returns true if obj contains k.
(j/contains? o :k)
(j/contains? o .-k)
Returns true if `obj` contains `k`. ``` (j/contains? o :k) (j/contains? o .-k) ```
getclj/s≠
(get obj k)(get obj k not-found)Returns the value mapped to key, not-found or nil if key not present.
(j/get o :k)
(j/get o .-k)
Returns the value mapped to key, not-found or nil if key not present. ``` (j/get o :k) (j/get o .-k) ```
get-inclj/s≠
(get-in obj ks)(get-in obj ks not-found)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.
(j/get o :k :fallback-value)
(j/get o .-k :fallback-value)
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. ``` (j/get o :k :fallback-value) (j/get o .-k :fallback-value) ```
lookupcljs
(lookup obj)Returns object which implements ILookup and reads keys from obj.
(let [{:keys [a b c]} (j/lookup o)]
...)
Returns object which implements ILookup and reads keys from `obj`.
```
(let [{:keys [a b c]} (j/lookup o)]
...)
```objclj/s≠
(obj & keyvals)Create JavaSript object from an even number arguments representing interleaved keys and values. Dot-prefixed symbol keys will be renamable.
(obj :a 1 :b 2 .-c 3 .-d 4)
Create JavaSript object from an even number arguments representing interleaved keys and values. Dot-prefixed symbol keys will be renamable. ``` (obj :a 1 :b 2 .-c 3 .-d 4) ```
push!clj/s≠
(push! a v)Adds v to end of array a and returns the mutated array.
(j/push! arr 10)
Adds `v` to end of array `a` and returns the mutated array. ``` (j/push! arr 10) ```
select-keysclj/s≠
(select-keys obj ks)Returns an object containing only those entries in o whose key is in ks.
(j/select-keys o [:a :b :c])
(j/select-keys o [.-a .-b .-c])
Returns an object containing only those entries in `o` whose key is in `ks`. ``` (j/select-keys o [:a :b :c]) (j/select-keys o [.-a .-b .-c]) ```
unchecked-setclj/s≠
(unchecked-set obj & pairs)(unchecked-set obj k val)unshift!clj/s≠
(unshift! a v)Adds v to the beginning of array a and returns the mutated array.
(j/unshift! arr 10)
Adds `v` to the beginning of array `a` and returns the mutated array. ``` (j/unshift! arr 10) ```
update!clj/s≠
(update! obj k f & args)'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.
(j/update! o :foo + 10)
(j/update! o .-foo + 10)
'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. ``` (j/update! o :foo + 10) (j/update! o .-foo + 10) ```
update-in!clj/s≠
(update-in! obj ks f & args)'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.
(j/update-in! o [:foo :goo] + 10)
(j/update-in! o [.-foo .-goo] + 10)
'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.
