quote.js

  async getQuote() {
    const catagories = ['inspire', 'funny', 'students', 'life', 'management', 'sports'];
    const randomCategory = Math.floor((Math.random() * (catagories.length - 1) + 0));

    const response = await fetch(this.state.source + catagories[randomCategory]);
    const data = await response.json();
    this.setState({
      quote: { 
        text: data.contents.quotes[0].quote,
        author: data.contents.quotes[0].author,
        twitterLink: this.tweetThis(data.contents.quotes[0].quote)
      }
