Tests:

named function passed as reference
function a(){ this.x++; } for(let ii = 0; ii < 100; ii++){ let b = {a, x: 0}; for(let i = 0; i < 100; i++) b.a(); }
multiple named functions instances
for(let ii = 0; ii < 100; ii++){ let b = {a(){ this.x ++}, x:0} for(let i = 0; i < 100; i++) b.a(); }
named arrow function refrence
const a = (b) => b.x++; for(let ii = 0; ii < 100; ii++){ let b = {a, x:0}; for(let i = 0; i < 100; i++) b.a(b); }
multiple anonymous functions instances
for(let ii = 0; ii < 100; ii++){ let b = {a: B => B.x++, x:0}; for(let i = 0; i < 100; i++) b.a(b); }
Class named function on prototype
class B{ x = 0; a(){ this.x++ } } for(let ii = 0; ii < 100; ii++){ let b = new B; for(let i = 0; i < 100; i++) b.a(); }
Class arrow function on prototype
class B{ x = 0; a = b => { b.x++ } } for(let ii = 0; ii < 100; ii++){ let b = new B; for(let i = 0; i < 100; i++) b.a(b); }
