Question

I am trying to create a simple a TODO list app in ReactJS. My basics of React are not very clear so I am stuck here.

Answer 1

you can go with Alex Solution but you can also achieve the same thing by changing only two place like

var that=this;
var createItem = function(item) {
      return 
{item.text}
;
    };
    return 
{this.props.items.map(createItem)}
;
