4.Python3 - 1991

Approach 1

number1 = 13
number2 = 31
string1 = "Welcome to TN34DeVs"
isAvailable = True

print(string1)
print("Number 1: ",number1,"Number 2: ",number2)
print("Total of Numbers 1 and 2 = ",(number1+number2))
print("The Boolean Value: ",isAvailable)

Approach 2

number1 = 13
number2 = 31
string1 = "Welcome to TN34DeVs"
isAvailable = True

print(string1)
print("Number 1: {0}, Number 2: {1}".format(number1,number2))
print(f"Total of Numbers 1 and 2 = {(number1+number2)}")
print(f"The Boolean Value: {isAvailable}")

5.JavaScript / Node.js - 1995/2009

Approach 1

number1 = 13

fmt.Printf("\nTotal of Numbers 1 and 2 = %d",number1+number2)
fmt.Printf("\nThe Boolean Value: %v",isAvailable)
}

Approach 2

package main
import "fmt"
