Get your shorts on - this is an array workout!

## Array Cardio Day 1

        
const inventors = [
      { first: 'Albert', last: 'Einstein', year: 1879, passed: 1955 },
      { first: 'Isaac', last: 'Newton', year: 1643, passed: 1727 },
      { first: 'Galileo', last: 'Galilei', year: 1564, passed: 1642 },
      { first: 'Marie', last: 'Curie', year: 1867, passed: 1934 },
      { first: 'Johannes', last: 'Kepler', year: 1571, passed: 1630 },
      { first: 'Nicolaus', last: 'Copernicus', year: 1473, passed: 1543 },
      { first: 'Max', last: 'Planck', year: 1858, passed: 1947 },
      { first: 'Katherine', last: 'Blodgett', year: 1898, passed: 1979 },
      { first: 'Ada', last: 'Lovelace', year: 1815, passed: 1852 },
      { first: 'Sarah E.', last: 'Goode', year: 1855, passed: 1905 },
      { first: 'Lise', last: 'Meitner', year: 1878, passed: 1968 },
      { first: 'Hanna', last: 'Hammarström', year: 1829, passed: 1909 }
];

const people = [
      'Bernhard, Sandra', 'Bethea, Erin', 'Becker, Carl', 'Bentsen, Lloyd', 'Beckett, Samuel', 'Blake, William', 'Berger, Ric', 'Beddoes, Mick', 'Beethoven, Ludwig',
      'Belloc, Hilaire', 'Begin, Menachem', 'Bellow, Saul', 'Benchley, Robert', 'Blair, Robert', 'Benenson, Peter', 'Benjamin, Walter', 'Berlin, Irving',
      'Benn, Tony', 'Benson, Leana', 'Bent, Silas', 'Berle, Milton', 'Berry, Halle', 'Biko, Steve', 'Beck, Glenn', 'Bergman, Ingmar', 'Black, Elk', 'Berio, Luciano',
      'Berne, Eric', 'Berra, Yogi', 'Berry, Wendell', 'Bevan, Aneurin', 'Ben-Gurion, David', 'Bevel, Ken', 'Biden, Joseph', 'Bennington, Chester', 'Bierce, Ambrose',
      'Billings, Josh', 'Birrell, Augustine', 'Blair, Tony', 'Beecher, Henry', 'Biondo, Frank'
];
    

1. Filter the list of inventors for those who were born in the 1500's

        
const born1500 = inventors.filter(inventor => inventor.year >= 1500 && inventor.year < 1600)
    

2. Give us an array of the inventors first and last names

        
const fullName = inventors.map(inventor => `${inventor.first} ${inventor.last}`)
    

3. Sort the inventors by birthdate, oldest to youngest

        
const sortBirth = inventors.sort((a,b) => a.year > b.year ? 1 : -1)
    

4. How many years did all the inventors live all together?

        
const lifeSpan_All = inventors.reduce((acc, c) => acc + (c.passed - c.year), 0)
    

5. Sort the inventors by years lived

        
const sortLived = inventors.sort((a,b) => {
    const aYears = a.passed - a.year
    const bYears = b.passed - b.year
	   if (aYears > bYears){
	       return 1
	   } else {
	       return -1
	   }
})
    

6. create a list of Boulevards in Paris that contain 'de' anywhere in the name

        
const container = document.querySelector('.mw-category')
const links = Array.from(container.querySelectorAll('a'))
    .map(link=> link.textContent)
    .filter(link=> link.includes('de'))
    

7. sort Exercise

        
const sortPeople = people.sort((a,b) => {
    const [aLast, aFirst] = a.split(', ')
    const [bLast, bFirst] = b.split(', ')
	if (aLast > bLast){
		return 1
	} else {
		return -1
	}
})
    

8. Reduce Exercise

        
const data = ['car', 'car', 'truck', 'truck', 'bike', 'walk', 'car', 'van', 'bike', 'walk', 'car', 'van', 'car', 'truck' ];
            
const countDataInstances = data.reduce((acc, c) => {
	if (!acc[c]) {
		acc[c] = 0
	}
	acc[c]++
	return a
}, {})
