TypeScript Bubble Sort

TIL

tsconfig.json

• create tsconfig.json automatically

tsc --init --rootDir "./src" --outDir "./build"

concurrently

• Run multiple commands concurrently
• npm

npm install --save-dev concurrently

• package.json

"scripts": {
    "start:run": "nodemon build/index.js",
    "start:tsc": "tsc -w",
    "start": "concurrently npm:start:*"
}

Abstract Classes

• Strongly couples classes together
• Informs child classes what methods they should have

abstract class Vehicle {
    abstract goTo(road: string): void
    abstract setOwner(name: string): void

    startEngine(): void {...}
}

class Car extends Vehicle {
    constructor() {
        super();
        ...
    }
}

Method Chaining

class Calculatr {
    constructor(public value: number) {}

    add(num: number): this {
        this.number += num;
        return this;
    }
}

const calc = new Calculator(1);
calc.add(1).add(10).add(4);
