I have the following JS code:
let a = false
let b = true
let c = [...(a ? {d: 1} : {})]
I'm trying to set c to [{d: 1}] if a is true, and set it to [] if a is false. It's throwing the error object is not iterable (cannot read property Symbol(Symbol.iterator))
Why is it throwing this error and how can I fix it?
You need to wrap the expressions in arrays.
const
a = false,
b = true,
c = [...(a ? [{ d: 1 }] : [])],
d = [...(b ? [{ d: 1 }] : [])];
console.log(c);
console.log(d);
