Esta es la primera vez que veo esta transformación de datos. Por favor, ayúdame con esto. ¡Gracias!

La pregunta proporciona una serie de pruebas. Necesitamos agregar el código para pasar las pruebas:

 describe('when receiving data for multiple points in time', () => { it('returns the expected output', () => { const input = [ { data: [[1242362340000, 10], [1242362340001, 4]] }, { data: [[1242362340000, 6], [1242362340001, 9]] }, { data: [[1242362340000, 11], [1242362340001, 13]] }, ]; const output = { 1242362340000: { x: 1242362340000, points: [10, 6, 11], total: 27, }, 1242362340001: { x: 1242362340001, points: [4, 9, 13], total: 26, } }; responseToTimeseries(input).should.deep.equal(output); }); }); describe('when some point is missing', () => { it('returns the expected output', () => { const input = [ { data: [[1242362340000, 20]] }, { data: [[1242362340000, 10], [1242362340001, 4], [1242362340002, 1]] }, { data: [[1242362340000, 6], [1242362340001, 9]] }, { data: [[1242362340000, 11], [1242362340001, 13], [1242362340002, 2]] }, ]; const output = { 1242362340000: { x: 1242362340000, points: [20, 10, 6, 11], total: 47, }, 1242362340001: { x: 1242362340001, points: [0, 4, 9, 13], total: 26, }, 1242362340002: { x: 1242362340002, points: [0, 1, 0, 2], total: 3, } }; responseToTimeseries(input).should.deep.equal(output); }); }); });
