Food for Thought
A mindset, an example, and an action item to start the week
❝

"Don’t be afraid to give up the good to go for the great."

John D. Rockefeller

Mindset: Settling for the good inhibits greatness; this quote inspires us to embrace risk and continuously strive for excellence.

Example: Amazon started as an online bookstore but wasn't afraid to expand into e-commerce, cloud computing, and other ventures, becoming a tech giant.

Action item: Identify one area where you're settling for good, and make a plan to pursue a great opportunity instead.

The Quick Byte
One coding tip because you’re technical after all

This week’s coding challenge:

Coding Challenge #60 - Pastebin

This challenge is to build your own version of a Pastebin.

This week’s tip:

Currying is a technique in functional programming where a function with multiple arguments is transformed into a sequence of functions, each taking a single argument.
Partial application is the process of applying some arguments to a function and returning a new function that accepts the remaining arguments.

Wen?

  • When you want to create reusable and composable functions by breaking down a function into smaller, specialized functions.

  • When you want to create higher-order functions that take other functions as arguments or return functions as results.

  • When you want to partially apply arguments to a function and create a new function with a pre-configured environment.

Why?

  • Promotes code reusability and modularity.

  • Enhances code readability by breaking down complex logic into smaller, more focused functions.

  • Enables functional composition and the creation of higher-order functions.
