JSFoo: round the year submissions

Submit talks on JavaScript and full stack engineering round the year

Is Type safety really needed in JavaScript?

Submitted by Souvik Basu (@souvikbasu) on Thursday, 25 January 2018

Technical level: Advanced Status: Awaiting details


Most JS frameworks and libraries today are opting for type safety to handle application complexity for large codebases. But is it really needed? Does that slow down development efforts and runtime performance? Or is it actually a good move?


  • JS as it was designed pre 2014
  • advent of TypeScript, Flow, PropTypes
  • When is type safety needed? When it is not?
  • Implication of type safety on JS code maintainability and writability
  • Implications on runtime performance

    Souvik, I need to see draft slides and preview video (explaining what this talk is about and why JSFoo participants should attend it). Without this, we cannot review the proposal.
