I'm trying to map some elements based on an arbitrary length.
I haven't been able to find anything online, but I'd like to do something like:
new Array(5).map(num => <input />)
but this doesn't seem to work.
A user would input a number, and then that many input fields should render.
What am I doing wrong here?
You need to fill the array before mapping, as map ignores empty slots.
new Array(5).fill().map(num => <input />)
However, Array.from would be more suitable in this case.
Array.from({length: 5}, ()=> <input />)
use fill then map the array
new Array(5).fill().map(num => <input />)
or you could use Array.from
Array.from(Array(5), ()=> <input />)
