TS HOME

TypeScript is a strongly typed programming language that builds on JavaScript, giving you better tooling and static type safety at compile time.

TS HOME (What is TypeScript?)

CONCEPT OVERVIEW

TypeScript serves as a strict syntactical superset of JavaScript, adding optional static typing layers.
Transpiles down to clean, cross-browser vanilla JavaScript code that runs on any JS runtime.
Identifies syntax errors, type mismatches, and undefined variable references during build steps.

interface Point {
    x: number;
    y: number;
}

function printCoordinates(pt: Point) {
    console.log(`Coords: x=${pt.x}, y=${pt.y}`);
}

// Object shape matches Point interface structure
const sample = { x: 10, y: 20, z: 30 };
printCoordinates(sample);
