🥕🍎 In command ts-node-dev --transpile-only tg.ts what does the flag do --transpile-only? (ChatGPT)

The --transpile-only flag in the ts-node-dev command tells TypeScript Node (ts-node) to skip type checking when running the TypeScript code. Normally, TypeScript checks the types as it compiles the code, which can slow down the process.

When using --transpile-only, TypeScript only transpiles the code (i.e., converts TypeScript to JavaScript) without performing any type checks. This can make the development process faster, especially in situations where you rely on external tools (like an IDE or a separate build step) to handle type checking.

Javascript Cheatsheet - Sahil

SLEEP FUNCTION
==============
await new Promise(r => setTimeout(r, 2000))


SLICE Array Method
==================
// Note:
// 1. slice() method returns shallow copied array.
// 2. first argument is inclusive and second argument is **non-inclusive**
const newArray = myArray.slice(startIdx, endIdx + 1);



SORTING Array Method
=======
myNumbers.sort(); // sorts in ascending order [DEFAULT]
myNumbers.sort((a, b) => a - b); // sorts in ascending order [DEFAULT]
myNumbers.sort((a, b) => b - a); // sorts in descending order



REDUCE ARRAY METHOD
======
ar = [ 1, 2, 3 ]
ar.reduce((a,b) => a+b, 0) // Output: 6



PUSH/POP/SHIFT/UNSHIFT - all mutate array
=====
`push` and `pop` works on end of array
`unshift` and `shift` works on start of array



USING FETCH
===========
// client-side
const response = await fetch('/roll'); // 'GET'
const { number } = await response.json();

const response = await fetch('/todo', {
	method: 'POST', // 'PUT', 'DELETE', 'PATCH'
	body: JSON.stringify({ description }),
	headers: {
		'Content-Type': 'application/json'
	}
});
const { description } = await response.json();

// server-side
const { description } = await request.json();



GETTER AND SETTERS IN AN OBJECT
===============================
// Example 1:
const obj = {
    countValue: 42,
    get count() {
        return this.countValue;
    },
    set count(value) {
        this.countValue = value;
    }
};

console.log(obj.count); // 42
obj.count = 43;
console.log(obj.count); // 43




// Example 2:
let input = {
    a: 1,
    b: 2,
    get sum() {
        return input.a + input.b;

    }
};

console.log(input.sum); // 3

input.a = 3;
input.b = 4;
console.log(input.sum); // 7




// Example 3:
function add(input) {
    return {
        get value() {
            return input.a + input.b;

        }
    };
}

let input = { a: 1, b: 2 };

let total = add(input);
console.log(total.value); // 3

input.a = 3;
input.b = 4;
console.log(total.value); //7




// WHEREAS FUNCTION DEFINED WITH `function` KEYWORD OR ARROW-FUNCTION-SYNTAX BEHAVES HAS GENERAL FUNCTIONS UNLIKE GETTER/SETTERS:
// -----------------------------------------------------------------------------------------------------------------------------
// Read more differenes here - https://github.com/sahilrajput03/sahilrajput03/blob/main/learn-js.md#geeter-setters-in-object
const obj = {
  countValue: 42,
  count: () => this.countValue, // Note: `this` here doesn't refer to the object.
};

console.log(obj.count()); // undefined, because `this` does not refer to `obj`.



~~
===============================
// In JS, the ~~ symbol is often referred to as the double tilde. It is a shorthand trick for converting a number to an integer by dropping its decimal part (similar to Math.floor() for positive numbers). ~~ relies on bitwise operations, which are implemented at a lower level in JavaScript. Using ~~ is limited to 32-bit signed integers. For usage with any numeric value please prefer using `Math.trunc()` instead. (from ChatGPT)
console.log(~~4.5);    // Output: 4
console.log(~~-4.5);   // Output: -4

A small scale is 15cm long.

Length 			
======
1 ft ≈ 30.48 cm
1 m ≈ 3.3 ft (precisely 3.28084)
1 m ≈ 39.4 inch (precisely 39.3701)
1 km ≈ 0.62 miles (precisely 0.621371)
1 mile ≈ 1.61 km (precisely 1.60934)

10^⁶ = 1 Million = 10 Lakh
10^⁹ = 1 Billion = 100 Crore
10^¹² = 1 Trillion = 100k Crore  =  100 Thousand Crore  =  1 Lakh Crore

Mass
====
1 kg ≈ 2.2 lbs (pounds)
1 lbs ≈ 0.45 kg

Currency
========
**For fastest conversion from dollar to inr you can simply multiply by 100 (~84 ₹/$).**

$ to ₹ Conversion factor: 83 ₹/$
₹ to $ Conversion factor: 0.012 $/₹

$ 1 Million  = ₹ 8.3 Crore
$ 1 Billion  = ₹ 8.3k Crore
$ 1 Trillion = ₹ 83 Lakh Crore = ₹ 8300k Crore

Conversion Trick For $ and ₹
============================
1. To convert $ to ₹ we can multiply the value with 10 and 8 in sequence. (Refer ^1 at bottom)
2. To convert ₹ to $ we can divide the value with 10 and 8 in sequence (Refer ^1 at bottom)

References
==========
^1: 10 and 8.3 are multiplicative factors of 83 because 10 x 8.3 equals 83.
