const newArr = arr.map((item) => [item.id, item.name]);
Using the map function in combination with Object.values
const newArray = array.map(item => Object.values(item));map each item utilizing Object.values.
const x = [
{"id" : 1, "name": "apple"},
{"id" : 2, "name": "banana"},
{"id" : 3, "name": "cherry"},
]
const y = x.map(Object.values);
console.log(y);Utilizing the map function
arr = [ {"id" : 1, "name": "apple"}, {"id" : 2, "name": "banana"}, {"id" : 3, "name": "carrot"} ]
result=arr.map(obj=>[obj.id,obj.name])
