valueMap(), outV() and similar traversals are spawned anonymously from a double underscore class - __ - so your code could be re-written as:

const gremlin = require('gremlin');
const __ = gremlin.process.statics;

g.V('test-id')  
    .bothE()  
    .limit(10)  
    .project('id', 'properties', 'out', 'in')  
    .by(id)  
    .by(__.valueMap())  
    .by(__.outV().id())  
    .by(__.inV().id())
