I used a bit different Approach, as we always know our actual components so i thought to apply switch case. Also total no of component were around 7-8 in my case.
getSubComponent(name) {
let customProps = {
"prop1" :"",
"prop2":"",
"prop3":"",
"prop4":""
}
switch (name) {
case "Component1": return <Component1 {...this.props} {...customProps} />
case "Component2": return <Component2 {...this.props} {...customProps} />
case "component3": return <component3 {...this.props} {...customProps} />
}
}
