Benchmark: FSM - Array spread vs Array push

Script Preparation code:

var languages = [
        { key: '1', label: 'One' },
        { key: '2', label: 'Two' },
        { key: '3', label: 'Three' },
        { key: '4', label: 'Four' },
        { key: '5', label: 'Five' },
        { key: '6', label: 'Six' },
    ];

Tests:

Spread
languages.reduce((acc, language) => { return [ ...acc, { name: language.key, value: language.key, label: language.label, }, ]; }, []);
Push
languages.reduce((acc, language) => { acc.push({ name: language.key, value: language.key, label: language.label, }); return acc; }, []);
