Rails Girls Summer of Code : 3 months journey of contributing to babel.js（Rails Girls Summer of Code で Babel.js に貢献した 3 ヶ月） Since July, I have worked for Babel.js as part of Rails Girls Summer of Code, a global fellowship program for women and non-binary coders.

Our team has developed REPL in babel official website, a playground for ES6; where user can write ES6 code, check the relevant code in ES5; and also the output.

In this talk, as a member of Open Source ecosystem, I am going to share my experiences and learning from project and program.
