How to get array subset in TypeScript

Answer 1

function getSubset(array: number[], startIndex: number, length: number): number[] {
    // Extract a subset of the array
    return array.slice(startIndex, startIndex + length);
}

const arr: number[] = [3, 7, 9, 0, 4, 2, 1, 8];
const startIndex: number = 2; // Start index for the subset
const len: number = 4;     // Number of elements in the subset

const subset: number[] = getSubset(arr, startIndex, len);

console.log("Subset: " + subset.join(", "));

  
  
/*
run:
  
"Subset: 9, 0, 4, 2" 
  
*/
