Рет қаралды 265
4 жыл бұрынPart-1 talks about higher order functions in Javascript and mental models of frequently used Higher order functions like map( ) of Array and connect( ) of Redux.
6:33 - connect( ) of redux
Remember that actual implementation of connect( ) would be a bit complex but this one gives a construct to think in that direction.
In Part-2, I will talk about how memory allocation, scope and closures work in higher order functions.

Small edit : I missed "return" in render. and For proper diff of states, oldState should be captured inside render() method. So that each time, component renders we should have the current oldState . this.oldState= mapStateToProps().. Go to gist link in description for corrected model
