Women Who Code Resources

Strategies

  • YAGNI vs. DRY
  • SOLID Principles
  • Ask clear questions -- explain what you have tried and what is not working
  • Don't reinvent the wheel -- evaluate best practices & existing solutions before attempting something novel
  • Follow conventions -- having the computer understand your code is easy; having other people understand your code is harder
  • Document & explain your decisions & understanding
