Is there a way to deconstruct an array, assign it to a variable, and then pass the value to another deconstructed variable all in one line of code? Take a look at what I want to achieve below:
const { prop } = [a] = chips.filter(x => x.id == 1);
Typically, this would be done in two lines of code like so:
const [a] = chips.filter(x => x.id == 1);
const { prop } = a;
Can this be accomplished on a single line?
Definitely! Just place the { prop } inside where the current a is:
const [{ prop }] = chips.filter(x => x.id == 1);
const chips = [
{ id: 1, prop: 'foo'},
{ id: 1, prop: 'bar'},
{ id: 1, prop: 'baz'}
];
const [{ prop }] = chips.filter(x => x.id === 1);
console.log(prop);(keep in mind that using strict equality comparison with === is recommended if possible)
However, if you only need to access the first matching element from the array, it's better to use .find instead of .filter, as .find returns the found element directly, whereas filter returns an array (which might not be necessary):
const chips = [
{ id: 1, prop: 'foo'},
{ id: 1, prop: 'bar'},
{ id: 1, prop: 'baz'}
];
const { prop } = chips.find(x => x.id === 1);
