Functions
Loops1. If:IF is used to execute a block of code based on a condition. Syntax
2. If-Else:Else part is used to execute the block of code when the condition fails. Syntax
3. Switch:Switch is used to replace nested If-Else statements. Syntax
4. ForFor loop is used to iterate a set of statements based on a condition.
5. WhileWhile is also used to iterate a set of statements based on a condition. Usually while is preferred when number of iterations are not known in advance.
6. Do-WhileDo-while is also used to iterate a set of statements based on a condition. It is mostly used when you need to execute the statements atleast once.
ClassesES6 introduced classes along with OOPS concepts in JS. Class is similar to a function which you can think like kind of template which will get called when ever you initialize class. Syntax:

How do you print a vowel in Javascript?Printing vowels in the string. let s = "welcome". let c, i.. for (i=0; i<=s. length-1; i++){. c = s[i] // or s.charAt(i). if (c=="a"|| c=="e" || c=="i" || c=="o". c=="A"|| c=="E"|| c=="I" || c=="O" || c==. log(c). How do I find a missing vowel in a String?To find the vowels in a given string, you need to compare every character in the given string with the vowel letters, which can be done through the charAt() and length() methods. charAt() : The charAt() function in Java is used to read characters at a particular index number.
How do you find the vowels in JS?In the above program, the user is prompted to enter a string and that string is passed to the countVowel() function.. The regular expression (RegEx) pattern is used with the match() method to find the number of vowels in a string.. The pattern /[aeiou]/gi checks for all the vowels (case-insensitive) in a string.. How do you check if a String contains a vowel in Javascript?To do this, we can use the includes method. The includes() method determines whether an array includes a certain value among its entries. It returns true if so, and false if not. Using includes , we'll check if our vowels array contains the character we're currently iterating over in our loop.
