Lesson 2

Strings in JavaScript

Your Name in Quotes

Store your name in a variable called name and print it.

let name = "Maya";
console.log(name);

Single vs Double Quotes

Write your favorite place using single quotes, then double quotes, and confirm both work.

let first = "Maya";
let last = "Putri";
console.log(first + " " + last);

Sticking Strings Together (+)

Combine your first and last name into a full name, with a space in between.

let first = "Maya";
let last = "Putri";
console.log(first + " " + last);

Template Literals (Backticks)

Rewrite Exercise 3 (full name) using backticks and ${} instead of +.

let name = "Maya";

let age = 10;

console.log(`My name is ${name} and I am ${age} years old.`);

String Length

Check the length of their name. Bonus: whose name in the group is the longest?

let word = "JavaScript";
console.log(word.length);

Shouting and Whispering

Introduce .toUpperCase() and .toLowerCase().
Task: Take their name and print a "shouting" version (all caps) and a "whispering" version (all lowercase).

let word = "hello";
console.log(word.toUpperCase());
console.log(word.toLowerCase());

Slicing a String

Use .slice() on your name to print just the first 3 letters (their "nickname").

let word = "JavaScript";
console.log(word.slice(0, 4));

Build a Name Badge

Fill in your own name, age, and favorite color, then run it to see their personalized badge pop up. Great for a "show and tell" moment at the end.

let name = "Maya";
let age = 10;
let favColor = "blue";
alert(`🪪 NAME BADGE 🪪
Name: ${name.toUpperCase()}
Age: ${age}
Favorite Color: ${favColor}
Nickname: ${name.slice(0, 3)}`);
