Meteor – unexpected token after Const

import {Component, PropTypes} from 'react';

var rbs = require('react-bootstrap'),
Panel = rbs.Panel;

export default class ResumeSection extends Component {< br /> constructor(...args) {
 super(...args);
 this.state = {
 open: true
 };
} 

 const title = (
 
Panel title

 );

 render() {
 return (< br /> 
 
Body

 
 );
 }
}

render() {
 const title = (
 
Panel title

 );
 // ...
}

When I try to specify a constant, I receive an unexpected token error in React, and I can’t seem to figure out the reason.

My code Very simple, I almost completely followed the react-bootstrap example here.

My code is as follows:

import {Component, PropTypes} from'react' ;

var rbs = require('react-bootstrap'),
Panel = rbs.Panel;

export default class ResumeSection extends Component {
 constructor(...args) {
 super(...args);
 this.state = {
 open: true
 };
 }

 const title = (
 
Panel title

 );

 render() {
 return (
 
 
Body

 
 );
 }
}< /pre> 
An error occurred directly after const, and it just said SyntaxError: Unexpected Token
You cannot define one in the class body like that const; it should be moved to a method. 
 
 
render() {
 const title = (
 
Panel title< /h3>
 );
 // ...
}
