I'm looking for the index of an item in an array of a list of objects by looking for a specific value inside of an object
currently, I'm doing this via
var x = [{ _id: '59974d9015a07e09b88e3b53', status: '1', id: '59974d2915a07e09b88e3b4b' }, { _id: '12345', status: '1', id: '54321' }]
var index = null;
for (var i=0; i<x.length; i++) {
if ( x[i]._id == '59974d9015a07e09b88e3b53' ) {
index = i;
break;
}
}

is there a more elegant solution via ES* where I wouldn't need to do a loop?
You can use findIndex()
method that returns index of first element that satisfies condition otherwise it returns -1.
var x = [{ _id: '59974d9015a07e09b88e3b53', status: '1', id: '59974d2915a07e09b88e3b4b' }, { _id: '12345', status: '1', id: '54321' }] var index = x.findIndex(e => e._id == '59974d9015a07e09b88e3b53') console.log(index)
