array filter how it works code example

Example 1: the filter array

var id = 2;
var list = [{
  Id: 1,
  Name: 'a'
}, {
  Id: 2,
  Name: 'b'
}, {
  Id: 3,
  Name: 'c'
}];
var lists = list.filter(x => {
  return x.Id != id;
})
console.log(lists);

Example 2: filter array by keyword

var data = [
  {email: "[email protected]",nama:"User A", Level:"Super Admin"},
  {email: "[email protected]",nama:"User B", Level:"Super Admin"},
  {email: "[email protected]",nama:"User C", Level:"Standart"},
  {email: "[email protected]",nama:"User D", Level:"Standart"},
  {email: "[email protected]",nama:"User E", Level:"Admin"},
  {email: "[email protected]",nama:"User F", Level:"Standart"}
];
var filter = "Level";
var keyword = "Standart";

var filteredData = data.filter(function(obj) {
	return obj[filter] === keyword;
});

console.log(filteredData);
