I am new to React.js and getting stuck loop thorough child ponent. I have an object and I need to loop through it which should create child ponent using the values of that object. Thank you in advance

var o = {
    playerA: {
        name: 'a',
    },

    playerB: {
        name: 'b',
    }
};


var Players = React.createClass({
    getPlayers: function(){
        return o;
    },    

    render: function() {
        return (
            <div>
                <div className="row"> Players</div>
                {this.getPlayers()}
                <Player /> 
            </div>
        );
    }
});


var Player = React.createClass({    
    render: function(){
        return (
            <div className="row" > player {this.name} < /div>
        )
    }
});

React.render(<Players />, document.getElementById('container'));

The result should be:

player a

player b

Reset to default 6

First, you'll iterate over the data with .map so that you can return markup (the child ponent) for each item. In the child ponent markup, you pass the data for that item in an attribute.

{Object.keys(yourObject).map(function(key) {
  return (
    // Add a key to the list item, it is mandatory from react
    // What the key consists of if it's the id or not is up to you
    // it needs to be unique though
    <ChildComponent key={key} data={yourObject[key]}/>
  );
})}

The child ponent's markup can then use that data by binding this.props.data.

<div>Player: {this.props.data.name}</div>

You don't have to use the name "data" for the attribute/property. Something like info={yourObject[key]} with this.prop.info is just as valid.
