數組對象取交集，差集，並集

前提聲明兩個數組

const arr1 = [{
   id: '5feb137ea68b1a5ed0547bdf',
}, {
   id: '5fe48ba3a68b1a1a26fc412c'
}, {
   id: '5fd7464aa68b1a56054d94da'
}];

const arr2 = [{
   id: '5fd7464aa68b1a56054d94da',
}, {
   id: '5fe48ba3a68b1a1a26fc412c',
}];

一、取交集

/**
 * @param invoice
 * @param select
 */
const intersectFn = (invoice = [], select = []) => {
   const intersection = invoice.filter(inv => select.some(sel => sel.id === inv.id));
   return [...intersection];
};

intersect(arr1, arr2);

二、取差集

/**
 * @param invoice
 * @param select
 */
const minusFn = (invoice = [], select = []) => {
   const minusion = invoice.filter(inv => select.every(sel => sel.id !== inv.id));
   return [...minusion];
};

minus(arr1, arr2);
