ECMA 6 - Test Arrow function

[emravera]

Generate suites for:

// Expression bodies

odds  = evens.map(v => v + 1)
pairs = evens.map(v => ({ even: v, odd: v + 1 }))
nums  = evens.map((v, i) => v + i)

// Statement bodies
nums.forEach(v => {
   if (v % 5 === 0)
       fives.push(v)
}) 

// Lexical this inside arrow
this.nums.forEach((v) => {
    if (v % 5 === 0)
        this.fives.push(v)
})
