Typescript - Finding Array Length
Create a function "arrLength" that takes an array as input that accept any type of array, calculate the number of elements present in it and return it. Use the function to find out the length of the array. Define proper types as and when required - return type and the param type of the function argument should be mentioned.
["hi", "there"]
Sample Output 1: 2
Sample Input 2: [1,5,4]
Sample Output 2: 3
function arrLength<T>(arr: T[]): number {
return arr.length;
}
// Sample Input 1
const array1: string[] = ["hi", "there"];
const result1: number = arrLength(array1);
console.log("Sample Output 1:", result1); // Output: 2
// Sample Input 2
const array2: number[] = [1, 5, 4];
const result2: number = arrLength(array2);
console.log("Sample Output 2:", result2); // Output: 3
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
