Javascript Practice 01: JS Hero - Variables


Question: 

Declare a variable firstname and initialize it with the value 'Lata'.





Answer: 

This is a fairly simple exercise. 
> Can declare variables in 3 ways. 
> var, let & const

var firstname = 'Lata'; or (pre - ES6 Variable) (function scoped)
let firstname = 'Lata'; or (ES6 Variables) (block scoped)
const firstname = 'Lata'; (ES6 Variables) (block scoped)

All the 3 options will work. 
They have different properties.  
You can refer to MDN Webdocs or W3Schools for further information.

  Question:  Write a Javascript function that accepts a string as a parameter and counts the number of vowels within the string.  Answer:  function vowelCount (str) {   let vowels = /[aeiou]/gi;   let result = str.match(vowels);   let count = result.length;   return count;       }; > we declare a function 'vowelCount'  > it has one parameter 'str', which is a string > we declare a variable 'vowels' and initialize it with the 5 vowels > the 'g' modifier is used on the 'vowels' variable to perform a global match  > a global match will find all matches and will not stop after finding the first match >  additionally   the 'i' modifier is used  on the 'vowels' variable to perform case insensitive matching > we declare another variable 'result' and initialize it with the result we get when we use the match () method on the 'str' parameter > the match() method searches a string for a ma...

  Question:  Write a function lcm that takes two natural numbers and calculates their least common multiple (lcm). The lcm of two natural numbers a und b is the smallest natural number that is divisible by a and b. Example: lcm(4, 6) should return 12. Answer:  function lcm(a, b) {   let theLCM = 0;   let remainderA;   let remainderB;   do {     theLCM++;     remainderA = theLCM % a;     remainderB = theLCM % b;   } while (remainderA !== 0 || remainderB !== 0)   return theLCM; } > we declare a function lcm > it has 2 parameters: 'a' and 'b' > we declare a variable 'theLCM' & initialize it with a value of 0;  > we declare 2 empty variables: 'remainderA' & 'remainderB'  > we open a do while loop  > do/while loop is a variant of the while loop > this loop will execute the code block once, before checking if the condition is true > then it will repeat the loop a...
