assocclj
(assoc map key val)(assoc map key val & kvs)assoc[iate]. When applied to a map, returns a new map of the same (hashed/sorted) type, that contains the mapping of key(s) to val(s). When applied to a vector, returns a new vector that contains val at index. Note - index must be <= (count vector).

assoc-inclj
(assoc-in m [k & ks] v)Associates a value in a nested associative structure, where ks is a sequence of keys and v is the new value and returns a new nested structure. If any levels do not exist, hash-maps will be created.

getclj
(get map key)(get map key not-found)Returns the value mapped to key, not-found or nil if key not present.
Returns the value mapped to key, not-found or nil if key not present.
get-inclj
(get-in m ks)(get-in m ks not-found)Returns the value in a nested associative structure, where ks is a sequence of keys. Returns nil if the key is not present, or the not-found value if supplied.
Returns the value in a nested associative structure, where ks is a sequence of keys. Returns nil if the key is not present, or the not-found value if supplied.
mergeclj
(merge & maps)Returns a map that consists of the rest of the maps conj-ed onto the first. If a key occurs in more than one map, the mapping from the latter (left-to-right) will be the mapping in the result.

select-keysclj
(select-keys map keyseq)Returns a map containing all the values of the selected keys when a resolvable sequence is supplied, otherwise, a containing only those entries in map whose key is in keys
Returns a map containing all the values of the selected keys when a resolvable sequence is supplied, otherwise, a containing only those entries in map whose key is in keys
update-inclj
(update-in m ks f & args)'Updates' a value in a nested associative 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, and returns a new nested structure. If any levels do not exist, hash-maps will be created.
