As has been mentioned, the inferred type of props is {one: string, two: string}.This means props.one could be any string (even though we see it is "one"), so when you write
In the previous lesson (1.3 -- Introduction to objects and variables), we covered how to define a variable that we can use to store values this lesson, we''ll explore how to actually put values

Building codes set minimum standards for structures and buildings to protect public health, safety, and welfare. Building code requirements related to installation, materials, wind resis-tance,

orldonline.com/2014/09/new-nec-codes-will-afect-installations-2.33 2014 NEC, Section 690.12.34 The rapid shutdown provisions require that, for conductors more than five feet in length inside a building, or more than ten feet from a PV array, control circuits as part of a rooftop PV system have the ability to reduce volta
PV mounting systems and devices: Devices and systems used for mounting PV modules that are also used to provide grounding of the module frames should be identified for the purpose of grounding solar panels. Adjacent modules: Devices identified and listed for bonding the metal frames of PV modules can bond one panel to an adjacent one.
It is assumed that aluminum framed photovoltaic (PV) panels mounted on a “post” and rail mounting system, the most common in the industry today, will be installed by the homeowner. While metering the system is encouraged, the specification does not address system wiring elements for associated system sensors or monitoring equipment.
Additionally, a clear 3-ft pathway needs to be available for firefighter access to the roof. NEC 690 defines electrical safety requirements for PV systems. Equipment grounding required: Exposed non-current-carrying metal parts of PV module frames, electrical equipment and conductor enclosures must be grounded.
The installation of photovoltaic panels on a building roof or integral with a building roof also raises other code issues (e.g., roof loading, wind loading, fire ratings, weather tightness, mounting systems, roof penetrations, etc.), which may also be relevant for systems mounted on or integral to a wall.
The structural requirements for mounting a PV array on a residential rooftop that are presented in this section are consistent with the approach taken by SolarAPP+.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
