you’re miss-reading this error. props
is not undefined, what is calling props
is undefined, which is the this
keyword. you can manually set the context of the map function by passing in a second parameter
this.props.buildings.map(this.renderBuildings, this)
or bind it inline
this.props.buildings.map(this.renderBuildings.bind(this))
