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

Script Preparation code:

let {
    a,
    b,
    c,
    d,
    e,
    f,
    g,
    h
} = new Proxy({}, {
    // lazy
    get(t, p) {
        let a = {
            __proto__: null,
            toString() {
                return p
            }
        }
        a[Symbol.toPrimitive] = a.valueOf = a.toString
        return a
    }
})

Tests:

+ operator
a+b+c+d+e+f+g+h
concat()
''.concat(a,b,c,d,e,f,g,h)
template interpolation
;`${a}${b}${c}${d}${e}${f}${g}${h}`
Array.prototype.join
;[a,b,c,d,e,f,g,h].join('')
