Currency Handling vs Third-Party Libraries

Developers should learn currency handling when building applications that involve money, such as payment gateways, shopping carts, invoicing systems, or financial dashboards meets developers should learn and use third-party libraries to accelerate development, reduce bugs by relying on well-maintained code, and focus on core application logic rather than low-level implementations. Here's our take.

Currency Handling

Nice Pick

Developers should learn currency handling when building applications that involve money, such as payment gateways, shopping carts, invoicing systems, or financial dashboards

Pros

• It's essential to avoid common pitfalls like using floating-point numbers for calculations (which can lead to rounding errors) and to ensure compliance with financial standards and local regulations
• Related to: bigdecimal, decimal-data-types

Cons

• Specific tradeoffs depend on your use case

Third-Party Libraries

Developers should learn and use third-party libraries to accelerate development, reduce bugs by relying on well-maintained code, and focus on core application logic rather than low-level implementations

Pros

• Specific use cases include adding authentication with libraries like Passport
• Related to: package-managers, dependency-management

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use Currency Handling if: You want it's essential to avoid common pitfalls like using floating-point numbers for calculations (which can lead to rounding errors) and to ensure compliance with financial standards and local regulations and can live with specific tradeoffs depend on your use case.

Use Third-Party Libraries if: You prioritize specific use cases include adding authentication with libraries like passport over what Currency Handling offers.

The Bottom Line

Currency Handling wins

Developers should learn currency handling when building applications that involve money, such as payment gateways, shopping carts, invoicing systems, or financial dashboards
