如何导入ES6？

Question

How can I translate var exec = require('child_process').exec ; to ES6? I know the following: import exec from 'child_process';

What I don't know is how to add the .exec at the end to the ES6 syntax.

How can I translate var exec = require('child_process').exec; to ES6?

You do:

import { exec } from 'child_process';

I know the following: import exec from 'child_process';

That's actually wrong, it is as I've done above. More on import here .

Otherwise, is simply:

import child_process from 'child_process';
const exec = child_process.exec;

You CANNOT do anything like:

import exec from 'child_process'.exec;
