Benchmark: Creating objects

Script Preparation code:

setC = v => o => ({
  a: o.a,
  b: o.b,
  c: v,
  d: o.d,
  e: o.e,
  f: o.f,
  g: o.g,
  h: o.h,
  i: o.i,
  j: o.j
})

o = {
  a: 1,
  b: 2,
  c: 3,
  d: 4,
  e: 5,
  f: 6,
  g: 7,
  h: 8,
  i: 9,
  j: 0
};

Tests:

Assign
assign = Object.assign({}, o, {c: 4});
Spread
spread = {...o, c: 4};
Literal
literal = setC(4)(o)
