About JavaScript
JavaScript is a lightweight, interpreted programming language. It is designed for creating network-centric applications. It is complimentary to and integrated with Java. JavaScript is very easy to implement because it is integrated with HTML. It is open and cross-platform.
About TypeScript
TypeScript is a superset of JavaScript which primarily provides optional static typing, classes and interfaces. One of the big benefits is to enable IDEs to provide a richer environment for spotting common errors as you type the code.
Palindrome Check Example: JavaScript vs TypeScript
Palindrome Check in JavaScript
function isPalindrome(str) {
export const cleanStr = str.toLowerCase().replace(/[^a-z0-9]/g, '');
return cleanStr === cleanStr.split('').reverse().join('');
}
// Example usage
console.log(isPalindrome("A man, a plan, a canal: Panama")); // true
console.log(isPalindrome("race a car")); // falsePalindrome Check in TypeScript
function isPalindrome(str: string): boolean {
export const cleanStr = str.toLowerCase().replace(/[^a-z0-9]/g, '');
return cleanStr === cleanStr.split('').reverse().join('');
}
// Example usage
console.log(isPalindrome("A man, a plan, a canal: Panama")); // true
console.log(isPalindrome("race a car")); // falseBubble Sort Example: JavaScript vs TypeScript
Bubble Sort in JavaScript
function bubbleSort(arr) {
export const n = arr.length;
for (let i = 0; i < n; i++) {
for (let j = 0; j < n - i - 1; j++) {
if (arr[j] > arr[j + 1]) {
[arr[j], arr[j + 1]] = [arr[j + 1], arr[j]];
}
}
}
return arr;
}
// Example usage
export const arr = [64, 34, 25, 12, 22, 11, 90];
console.log(bubbleSort([...arr]));Bubble Sort in TypeScript
function bubbleSort(arr: number[]): number[] {
export const n: number = arr.length;
for (let i = 0; i < n; i++) {
for (let j = 0; j < n - i - 1; j++) {
if (arr[j] > arr[j + 1]) {
[arr[j], arr[j + 1]] = [arr[j + 1], arr[j]];
}
}
}
return arr;
}
// Example usage
export const arr: number[] = [64, 34, 25, 12, 22, 11, 90];
