Hello! I made a small (30 splashes) program that displays Minecraft Splash Text. Each time you run the program one of 30 lines is displayed.
Take a look and it and please give me feedback on how I can make it better.
Keep in mind I am a TOTAL newbie to JS 
console.log("Today's random Minecraft splash is:");
//calculates a random number between 1 and nam
const randomSplash = {
random(nam) {
let calc = Math.floor(Math.random() * nam) + 1;
return calc;
}
}
//the number 30 can be replaced with any other number
//the program will then generate a number between 1 and that number
let result = randomSplash.random(30)
//All the if instances for each number
if (result === 1) {
console.log("1. As seen on TV!")
} else if (result === 2) {
console.log("2. Awesome!")
} else if (result === 3) {
console.log("3. 100% pure!")
} else if (result === 4) {
console.log("4. May contain nuts!")
} else if (result === 5) {
console.log("5. More polygons!")
} else if (result === 6) {
console.log("6. Moderately attractive!")
} else if (result === 7) {
console.log("7. Limited edition!")
} else if (result === 8) {
console.log("8. Flashing letters!")
} else if (result === 9) {
console.log("9. It's here!")
} else if (result === 10) {
console.log("10. Best in class!")
} else if (result === 11) {
console.log("11. It's finished!")
} else if (result === 12) {
console.log("12. Kind of dragon free!")
} else if (result === 13) {
console.log("13. Excitement!")
} else if (result === 14) {
console.log("14. More than 500 sold!")
} else if (result === 15) {
console.log("15. One of a kind!")
} else if (result === 16) {
console.log("16. Heaps of hits on YouTube!")
} else if (result === 17) {
console.log("17. Indev!")
} else if (result === 18) {
console.log("18. Spiders everywhere!")
} else if (result === 19) {
console.log("19. Check it out!")
} else if (result === 20) {
console.log("20. Holy cow, man!")
} else if (result === 21) {
console.log("21. It's a game!")
} else if (result === 22) {
console.log("22. Made in Sweden!")
} else if (result === 23) {
console.log("23. Uses LWJGL!")
} else if (result === 24) {
console.log("24. Reticulating splines!")
} else if (result === 25) {
console.log("25. Minecraft!")
} else if (result === 26) {
console.log("26. Yaaay!")
} else if (result === 27) {
console.log("27. Singleplayer!")
} else if (result === 28) {
console.log("28. Keyboard compatible!")
} else if (result === 29) {
console.log("29. Ingots!")
} else if (result === 30) {
console.log("30. Exploding creepers!")
} else {
console.log("Error")
}
