A very good W3school tutorial can be found here.

Javascript – I don't know where I'm making mistake in Math.floor and Math.random?

I learned math.random and math.floor through websites but still stuck in the middle of my code. I’m newbie js is my first language.

//Create a business name generator by combining list of Adjective and Shop name and Another Word 

let a = math.floor(math.random() * 3);
let b = math.floor(math.random() * 3);
let c = math.floor(math.random() * 3);

let Adjectives = {
    0: Crazy,
    1: Amazing,
    2: Fire,
}

let ShopName = {
    0: Engine,
    1: Foods,
    2: Garments,
}

let AnotherWords = {
    0: Bros,
    1: Limited,
    2: Hub,
}

console.log(`${Adjectives[a]} ${ShopName[b]} ${AnotherWords[c]}`);

Expected answer = Crazy Engine Limited/ Amazing Garments Bros (Any 3 words combining and making a name)

    It’s a type-o

    math should be Math 🙂

    edit: Also, your Adjectives, ShopName and OtherWords should be arrays and not object.

    example:

    //Create a business name generator by combining list of Adjective and Shop name and Another Word 

const a = Math.floor(Math.random() * 3);
const b = Math.floor(Math.random() * 3);
const c = Math.floor(Math.random() * 3);

const adjectives = ['Crazy', 'Amazing', 'Fire'];

const shopName = ['Engine', 'Foods', 'Garments'];

const anotherWords = ['Bros', 'Limited', 'Hub'];

console.log(`${adjectives[a]} ${shopName[b]} ${anotherWords[c]}`);

    1. Math is written with a capital letter
    2. Your words are not variables so you must write it in ""
    //Create a business name generator by combining list of Adjective and Shop name and Another Word 

let a = Math.floor(Math.random() * 3);
let b = Math.floor(Math.random() * 3);
let c = Math.floor(Math.random() * 3);

let Adjectives = {
    0: "Crazy",
    1: "Amazing",
    2: "Fire",
}

let ShopName = {
    0: "Engine",
    1: "Foods",
    2: "Garments",
}

let AnotherWords = {
    0: "Bros",
    1: "Limited",
    2: "Hub",
}

console.log(`${Adjectives[a]} ${ShopName[b]} ${AnotherWords[c]}`);

    You can either use the default Math library or import a library such as maths to get your expected outcome. Here, I suppose you are trying to use the default math library (i.e. Math).

    Also please make sure that your string values must be within quotes (").

    let a = Math.floor(Math.random() * 3);
let b = Math.floor(Math.random() * 3);
let c = Math.floor(Math.random() * 3);

let Adjectives = {
    0: "Crazy",
    1: "Amazing",
    2: "Fire",
}

let ShopName = {
    0: "Engine",
    1: "Foods",
    2: "Garments",
}

let AnotherWords = {
    0: "Bros",
    1: "Limited",
    2: "Hub",
}

console.log(`${Adjectives[a]} ${ShopName[b]} ${AnotherWords[c]}`);

    Alternatively, you can use a list instead of a numbered directory.

    let Adjectives = ["Crazy", "Amazing", "Fire"]
