Tests:

  • lodash map

     
    const aux = [];
    _.map(data, el => {aux.push(el.filtering)});

  • lodash forEach

     
    const aux = [];
    _.forEach(data, el => {aux.push(el.filtering)});

  • native for

     
    const aux = [];
    for (let index = 0; index < data.length; index++) {
      const el = data[index];
      aux.push(el.filtering)
    }

  • native map

     
    const aux = [];
    data.map(el => {aux.push(el.filtering)})
