+Kloonige https://bitbucket.org/mkalmo/i399exlang repo ja importige see IDE-sse.
+
+1. Kirjutage funktsioon filter(array, predicateFunction), mis tagastab listi
+   elementidest, mis vastavad predicateFunction-iga määratud tingimusele.
+   kasutamise näide:
+   var oddNumbers = filter([1, 2, 3], function (each) {
+      return each % 2 === 1;
+   });      
+
+   Käivitamiseks: node ex1.js
+
+2. Kirjutage kood, mis:
+   - loob listi arvudega 1, 2, 3, 4, 5, 6
+   - lisab sinna arvud 7 ja 8
+   - filtreerib välja paarisarvud
+   - võtab need paarisarvud ruutu
+   - väljastab tulemuse konsooli
+   
+   kasutage array meetodeid .filter() ja .map()
+
+3. Kirjutage kood, mis väljastab nende elementide id-d, 
+   millel on "selected" tunnus tõene.
+
+4. Tehke objekt person, millel on väli name ja meetod getName(), mis tagastab nime.
+   Konstruktorile saab argumendiga nime ette anda.
+
+   var person = new Person("Jack");
+   console.log(person.getName()); // Jack
+   
+   Proovige panna meetodit nii objekti, kui prototüübi külge.
+   Veenduge, et meetod on õiges kohas (vihjed: Object.keys() ja __proto__).
+   
+5. Teil on kasutada funktsioon factorial(n, callback). 
+   Arvutage selle abil 5! ja printige see konsooli. 
+   Funktsiooni factorial ennast muuta ei tohi.
+
+6. Minge käsureal omale kloonitud repo kataloogi ja käivitage käsud: 
+   > npm install 
+   See laeb vajalikud teegid.
+   > npm start
+   See käivitab rakenduse, mis pakub aadressilt http://localhost:3000 järgmisi teenuseid:
+   
+   /api/persons/2948
+     Tagastab ID järgi isiku andmed (sh koodi).
+   
+   /api/health-insurance/<code>
+     Ütleb, kas sellise koodiga inimene on kindlustatud.
+
+   /api/tax-debt/<code>
+     Ütleb, kas sellise koodiga inimensel on maksuvõlg.
+
+   Kasutage neid teenuseid andmete saamiseks ja printige konsooli isiku andmed kujul:
+   {
+      name : <nimi>,
+      isInsured: <kas on kindlustatud>,
+      taxDebt: <maksuvõla suurus>
+   }
+   
+   Teenuste poole pöördumiseks:
+   get('/api/persons/2948', callbackFunktsioon);
+
