Typescript
Hello, I'm Sheheryar Altaf, a BSCS student at COMSATS University Islamabad. Passionate about computer science, I'm dedicated to mastering Object-Oriented Programming (OOP), Data Structures and Algorithms (DSA), and databases.
I have practical experience in projects like the Voting Management System database, where I've applied these skills hands-on.
I'm eager to tackle new challenges and continuously expand my knowledge and skills in computer science. Here's to excelling in my studies and embracing endless possibilities!
Optional Parameters
Use a question mark (?) for optional parameters.
function greetWithTitle(title: string, name?: string): string {
return `Hello, ${title}${name ? ' ' + name : ''}!`;
}
Arrow Functions
Arrow functions are concise. For a single statement, you can omit curly braces:
const add = (a: number, b: number): number => a + b;
Array Methods: forEach, map, and filter
The forEach Method
Iterate over array elements easily.
let fruits: string[] = ["banana", "mango", "apple", "cherry"];
fruits.forEach((fruit) => console.log(fruit));
The map Method
Create a new array by applying a function to each element.
const numbers = [1, 2, 3, 4, 5];
const doubled = numbers.map((num) => num * 2);
console.log(doubled); // Output: [2, 4, 6, 8, 10]
The filter Method
Create a new array containing elements that pass a test.
const ages = [15, 20, 17, 30, 14];
const adults = ages.filter((age) => age >= 18);
console.log(adults); // Output: [20, 30]
