call a function inside a module in ES6

Question

I may be confusing OO with JS modules but I want to do something like this:

export default {
    functionA:()=>{
        this.functionB
    },
    functionB:()=>{
        console.log('Hello from functionB')
    },
}

then:

import pc from 'path/to/pc'

pc.functionA

desired result: 'Hello from functionB'

actual result: TypeError: Cannot read property 'functionB' of undefined

What is the correct way to do this?? Is it even possible? Any help would be greatly appreciated.
