I’m trying to create a new obj similar to my input, but containing only the elements from a selected id list.
const arrObj = [ { value = 1, name = 'a' }, { value = 2, name = 'e' }, { value = 3, name = 'i' }, { value = 4, name = 'o' }, { value = 5, name = 'u' }, ]; const selectedIds = [1,4,5]; // How can I make this selectedObjs as the same type as arrObj, but only containing the selected elements? const selectedObjs = [];

Answer
Use Array.filter
const arrObj = [ { value: 1, name: "a", }, { value: 2, name: "e", }, { value: 3, name: "i", }, { value: 4, name: "o", }, { value: 5, name: "u", }, ]; const selectedIds = [1, 4, 5]; const selectedObjs = arrObj.filter(node => selectedIds.includes(node.value)); console.log(selectedObjs)
