49: Kotlin DevX at Instagram
Lisa works on the Dev Craft team at Instagram that embarked on a journey to bring Kotlin to the Instagram for Android code base a little over three years ago. Now, nearly half of the large codebase is migrated and over 80% of newly committed code is in Kotlin. Tune in to hear what the unique challenges of bringing a new language to an existing app are and what it means for build speed, IDE experiences and developer happiness.
