💻 The Talks
Charlotte Isambert, Fullstack mobile developper at discussing “You can’t use hooks conditionally… or can you?” 20-30mins
It’s the hooks rule number one: “Only call hooks at the top level”. But what if I told you that this rule does not apply to every hook? One of them can actually safely be used conditionally. To understand how useContext is different from other hooks, and why it is exempted from this major rule, we need to know why this rule exists in the first place. We will build our own mental model of react’s rendering behavior, focused on how react keeps track of data at runtime: props, states, refs… and context values.
Mohammad Javad, Head of Mobile at Theodo UK discussing “Monzo’s Spent This Month Widget” 10 mins
George Alexiou, Full-Stack Software Engineer at Theodo UK discussing “Apple Health Rings in React Native” 10 mins
Angus Findlay & Daniel Belo Goncalves, Co-Founder of 575 discussing "Tiny haiku app, written in react native, for next gen poets” 10 mins

Over the last 10 years and across over 500 projects, we have partnered with non-technical founders to launch their first product, FTSE 100 companies to increase market share through launching internal startups & spearheading digital transformation initiatives, and SME CTOs to build and scale their technical teams.
