🚀 What I Did

• Timetable using HTML.

🧠 What I Learned

JavaScript

let greeting = "hello";
console.log(greeting[greeting.length - 1]); // Output: "o"

let firstTwo = greeting[0] + greeting[1]; // Output: "he"
console.log(firstTwo);

• Bracket notation - Access specific characters in the string using their index.

let statement = "She said, \"Hello!\"";
console.log(statement); // Output: She said, "Hello!"

• We can use \\ and place our quotes in it.

Template Literal

const name = "Alice";
const age = 25;
const message = `My name is ${name} and I am ${age} years old.`;
console.log(message);

• String Interpolation - Inserting variables and expressions directly into a string.
• Template literals preserve line breaks without needing escape characters.

let sentence = "JavaScript is awesome!";
let position = sentence.indexOf("awesome!");
console.log(position); // 14

• indexOf() - used to find the index.

let sentence = "JavaScript is awesome!";
let position = sentence.indexOf("fantastic");
console.log(position); // -1

Prompt

let age = prompt("How old are you?");
if (age !== null) {
  console.log("You are " + age + " years old.");
} else {
  console.log("User canceled the prompt.");
}

• Displays a pop-up asking for user input and returns the input as a string.
• If you cancel prompt it returns null.
• Second argument is setting a default value in the input field.

🔥 What’s Next

• Advance strings.
