What is TypeScript?
TypeScript is a strongly-typed programming language that extends JavaScript with optional static types. It’s a syntactical superset of JavaScript, meaning any valid JavaScript code is also valid TypeScript code.
By adding features like static typing, interfaces, and advanced tooling, TypeScript helps developers write more reliable, maintainable, and scalable code. It’s widely used in modern web development, especially for large-scale applications.

TypeScript Syntax
// TypeScript program to solve a quadratic equation
let root1: number, root2: number;
// Take input from the user
const a: number = parseFloat(prompt("Enter the first number: "));
const b: number = parseFloat(prompt("Enter the second number: "));
const c: number = parseFloat(prompt("Enter the third number: "));
// Calculate discriminant
const discriminant = b * b - 4 * a * c;
// Condition for real and different roots
if (discriminant > 0) {
root1 = (-b + Math.sqrt(discriminant)) / (2 * a);
root2 = (-b - Math.sqrt(discriminant)) / (2 * a);
// Result
console.log(`The roots of the quadratic equation are ${root1} and ${root2}`);
}
// Condition for real and equal roots
else if (discriminant === 0) {
root1 = root2 = -b / (2 * a);
// Result
console.log(`The roots of the quadratic equation are ${root1} and ${root2}`);
}
// If roots are not real
else {
const realPart = (-b / (2 * a)).toFixed(2);
const imagPart = (Math.sqrt(-discriminant) / (2 * a)).toFixed(2);
// Result
console.log(
`The roots of the quadratic equation are ${realPart} + ${imagPart}i and ${realPart} - ${imagPart}i`
);
}
What is Minification?
Minification is the process of minimizing code and markup in your web pages and script files. It’s one of the main methods used to reduce load times and bandwidth usage on websites. Minification dramatically improves site speed and accessibility, directly translating into a better user experience. It’s also beneficial to users accessing your website through a limited data plan who would like to save on their bandwidth usage while surfing the web.
Why minify TypeScript?
When creating TypeScript, developers often use spacing, comments, and well-named variables to make code readable for themselves and others who might later work on the codebase. While this is beneficial during development, it becomes a disadvantage when serving your web pages. Web servers and browsers can parse file content without comments and well-structured code, both of which create additional network traffic without providing any functional benefit.
To minify TypeScript files, comments and extra spaces need to be removed, and variable names should be shortened to minimize code and reduce file size. The minified file version provides the same functionality while reducing the bandwidth of network requests.
Examples
Before minified
// TypeScript program to find the HCF or GCD of two integers
let hcf: number;
// Take input
const number1: number = parseInt(prompt('Enter a first positive integer: '));
const number2: number = parseInt(prompt('Enter a second positive integer: '));
// Looping from 1 to number1 and number2
for (let i = 1; i <= number1 && i <= number2; i++) {
// Check if i is a factor of both integers
if( number1 % i === 0 && number2 % i === 0) {
hcf = i;
}
}
// Display the HCF
console.log(`HCF of ${number1} and ${number2} is ${hcf}.`);
After minified
let hcf:number;const number1:number=parseInt(prompt('Enter a first positive integer: '));const number2:number=parseInt(prompt('Enter a second positive integer: '));for(let i=1;i<=number1&&i<=number2;i++){if(number1%i===0&&number2%i===0){hcf=i}}console.log(`HCF of ${number1} and ${number2} is ${hcf}.`);
