Javascript Shorts - 4 | Datatype Conversion - Part 1, Implicit Datatype, Explicit Datatype | ⁨@MindCodeTerux⁩ ​

JavaScript allows conversion between different data types explicitly (manually) and implicitly (automatically). These conversions happen when using operators, functions, or assignments.

🔹 Types of Data Type Conversion in JavaScript
There are two main types of conversions:

✅ Explicit Conversion (Type Casting)
Done manually using built-in methods like String(), Number(), Boolean(), parseInt(), parseFloat(), etc.

Example: Number("123") → Converts string "123" to number 123.

✅ Implicit Conversion (Type Coercion)
Done automatically by JavaScript when an operation requires a specific type.

Example: "5" + 2 → "52" (number 2 is converted to a string).

🔹 String Conversion
📌 Explicit String Conversion
Use String(value) or value.toString()

console.log(String(123)); // "123"
console.log(String(true)); // "true"
console.log(String(null)); // "null"
console.log((123).toString()); // "123"

📌 Implicit String Conversion
Happens when using + operator with a string.

console.log("Hello " + 123); // "Hello 123"
console.log(5 + "10"); // "510"
console.log(true + " World"); // "true World"

🔹Number Conversion
📌 Explicit Number Conversion
Use Number(value), parseInt(), or parseFloat()

console.log(Number("123")); // 123
console.log(Number("123abc"));// NaN (Not a Number)
console.log(parseInt("123px")); // 123
console.log(parseFloat("12.34")); // 12.34
console.log(Number(true)); // 1
console.log(Number(false)); // 0
console.log(Number(null)); // 0
console.log(Number("")); // 0

📌 Implicit Number Conversion
Happens in arithmetic operations (-, *, /) and comparisons.

console.log("5" - 2); // 3 (string "5" converted to number)
console.log("6" * "3"); // 18 (both converted to numbers)
console.log("10" / "2"); // 5 (both converted to numbers)
console.log("4" - true); // 3 (true = 1)

🔹 Boolean Conversion
📌 Explicit Boolean Conversion
Use Boolean(value)

console.log(Boolean(1)); // true
console.log(Boolean(0)); // false
console.log(Boolean("Hello")); // true
console.log(Boolean("")); // false
console.log(Boolean(null)); // false
console.log(Boolean(undefined)); // false

📌 Implicit Boolean Conversion
Happens in logical operations like if, ||, &&.

console.log(!!"Hello"); // true
console.log(!!0); // false
console.log(!!""); // false
console.log(!!undefined); // false

if ("text") { console.log("Truthy!"); } // This runs (truthy)
if (0) { console.log("Falsy!"); } // This does NOT run (falsy)
