Ternary Operator

[cyouh95]

Alternatively, you could use the ternary operator to help you simplify this:

playlistHero/src/components/Track/Track.js

Lines 14 to 20 in d05abe6

	renderAction(){
	if (this.props.isRemoval) {
	return (<a className="Track-action" onClick={this.removeTrack}>-</a>);
	} else {
	return (<a className="Track-action" onClick={this.addTrack}>+</a>);
	}
	}

to:

<a className="Track-action" onClick={this.props.isRemoval ? this.removeTrack : this.addTrack}>{this.props.isRemoval ? '-' : '+'}</a>

This a element could be placed directly in your render() method so you could omit the renderAction() method as well!
