How to print array elements in groups of 2 with TypeScript

Answer 1

const array: number[] = [1, 2, 3, 4, 5, 6, 7, 8];
const len: number = array.length;
 
// Group elements by 2 and print
for (let i: number = 0; i < len; i += 2) {
    const group: number[] = array.slice(i, i + 2);
    console.log(group);
}
 
 
      
/*

[1, 2] 
[3, 4] 
[5, 6] 
[7, 8]
