With map method and Object.values

let newArr = a.map(x => Object.values(x));

map each element using Object.values.

const  a = [
 {"id" : 1, "name": "a"},
 {"id" : 2, "name": "b"},
 {"id" : 3, "name": "c"},
]
const b = a.map(Object.values);
console.log(b);

Using map

a = [ {"id" : 1, "name": "a"}, {"id" : 2, "name": "b"}, {"id" : 3, "name": "c"} ]
r=a.map(o=>[o.id,o.name])
console.log(r)
