<!--your preparation HTML code goes here-->

Script Preparation code:

class ArrowMethod {
    constructor() {

    }
    method = () => {}
}
class BindMethod {
    constructor() {
        this.method.bind(this)
    }
    method() {}
}
class NoBind {
    constructor() {

    }
    method() {}
}
const n = new NoBind()
const a = new ArrowMethod()
const b = new BindMethod()

Tests:

create 1000 instances call arrow method
for (let i=0;i<1000;i++){ new ArrowMethod().method() }
create 1000 instances call bind method
for (let i=0;i<1000;i++){ new BindMethod().method() }
create 1000 instances call no bind method
for (let i=0;i<1000;i++){ new NoBind().method() }
