React

"React is a declarative, efficient, and flexible JavaScript library for building user interfaces."

Compared to other frameworks:

• 120KB, pretty large, but no required dependencies
• Fast
• Less DSL - "domain specific language" (vs. Angular, Ember)
• React Native for iOS and Android apps
• Supports server-side rendering

#Scope in Ruby

def longest_palindrome(words)
  words.split.each do |word|
    #Initialize current longest palindrome 
    curr_palindrome = ""
    
      #replace current palindrome if longer 
      curr_palindrome = word if word.length > curr_palindrome.length && palindrome?(word)

#JS Algorithm Problems

Write a method no_dupes which will take an array and return that same array with all duplicate items removed. Assume integers. This should be done without using uniqueness methods like Ruby's uniq.

// No Dupes in action:

// no_dupes( [ 1, 4, 2, 7, 3, 1, 2, 8 ] ); // #=> [ 1, 4, 2, 7, 3, 8 ]

no_dupes( [ 100, 32, 44, 44, 23, 32, 44 ] )

Outreach Resources

Out of the Office

OOTH was made to help connect tech newbies with experienced people in tech.

I talked to a former bootcamp grad in LA who now manages a team of React software engineers based in LA. I showed her my final project readme and she answered my questions about interviewing, company selection, self-study after graduation, etc. Highly recommended!

*I chose to talk to the person most similar to me, but they have quite a range of hella impressive people, in tech and tech-adjacent fields, including design, product, fintech, VC, data science, UI/UX, etc!

For example, January 2017 volunteers include:
