simple function	24452.1 Ops/sec
higher order function	47806.2 Ops/sec

Script Preparation code:

var artifacts = {
    getById: () => [Math.random()]
}

function flatten(artifacts, artifactId) {
    const getDependencies1 = (artifactId) => artifacts.getById(artifactId);
    return [
        ...getDependencies1(artifactId)
    ]
}

function createFlattenr(artifacts){
    const getDependencies2 = (artifactId) => artifacts.getById(artifactId);
    return (artifactId) => {
        return [
            ...getDependencies2(artifactId)
        ]
    }
}

Tests:

simple function
for(var i = 0; i < 100; i++) { flatten(artifacts, i) }
higher order function
const f = createFlattenr(artifacts) for(var i = 0; i < 100; i++) { f(i) }
