New to react world, trying to learn destructuring, have been reading about it but stuck here, if i do it like this function MList({action}) { // const data = [action];} i am just getting ‘cameras’. So how to destructure and get same result as with props below this is Mcard.js:
<Box pt={1}> <MList action="cameras" /> </Box>
This is inside MList komponent:
i want to destructure this code ( works gives ‘name’ and ‘ident’):
function MList(props) { const initialize = () => { const data = props[props.action]; if (!data || data.length < 1) { return; } data.map((e) => { collapseStates["" + e.name + e.ident] = false; return; }); setCollapseS(collapseS); }; }

I don’t know React but destructuring the arguments should be something like the following
function MList({action, ...tail}) { const initialize = () => { const data = tail[action]; if (!data || data.length < 1) { return; } data.map(({name, ident}) => { collapseStates["" + name + ident] = false; return; }); setCollapseS(collapseS); }; }
Also I would suggest using data.forEach
instead of data.map
if you don’t need to save the result in another array
