var array1 = [{name: 'foo', value: 3},{name:'bar', value: 4},{name:'x', value: 0}] var array2 = [{name: 'foo', type: 'a'},{name:'baz', type:'b'},{name:'x', type:'c'}]
Tests:
_.differenceBy
var difference = _.differenceBy(array1, array2, 'name')
Native
if (array1) { if (array2) { var difference = [array1.map(a => a.name), array2.map(a => a.name)] .reduce((a, b) => a.filter(c => !b.includes(c))) } else { array1 } }
