Tuples are immutable, meaning that they cannot be changed after they are created, while lists are mutable. Tuples are also more memory-efficient than lists and can be used as keys in dictionaries, while lists cannot. Additionally, tuples are often used to represent fixed structures with a ...
string: immutable string = 'abc'; string[-1] # note indexing is cardinal, not ordinal like R tuple: immutable tuple = (5, 3, 8); tuple[3] tuple2 = (tuple, 2, 14) # nested tuple int: immutable integer float: immutable floating point number list: mutable, uses append list ...
Mutable state Haskell does not support mutable state. All variables are constants and all values immutable. But the State type can be used to emulate programming with mutable state: add2 :: State Integer Integer add2 = do -- add 1 to state x <- get put (x + 1) -- increment in ano...
The new structolc_node_headeris introduced with a mutable lock and an optionalcheck_on_deallocin debug mode. This is helpful for concurrency checks, but confirm that all concurrency edge cases, especially with multiple threads deallocating nodes, are properly tested. Line range hint59-85:Assess n...
Side note: the ref you get from forwardRef is mutable so you can assign to it if needed. This was done on purpose. You can make it immutable if you have to - assign React.Ref if you want to ensure nobody reassigns it: import { forwardRef, ReactNode, Ref } from "react"; interface...
