var colors= ["red","blue"];
	colors.push("yellow"); 

var a=[], b={};
a.push(b);    
// a[0] === b;

var select =[2,5,8];
var filerdata=[];
for (var i = 0; i < select.length; i++) {
  filerdata.push(this.state.data.find((record) => record.id == select[i]));
}
//I have a data which is object,
//find method return me the filter data which are objects
//now with the push method I can make array of objects

var object = "Some Object"
var array = []

array.push(object)

let obj = { name: 'Bob' };
let arr = [{ name: 'John' }];

// add obj to array
arr = [...arr, obj];

console.log(arr) // [{ name: 'Bob' }, { name: 'John' }];
