Nested For Loop in JavaScript

In JavaScript, a nested "for" loop is a loop inside another loop. It allows you to create more complex looping structures to handle multidimensional data or perform repetitive tasks involving multiple sets of data.

Syntax:
       for (let i = 0; i < outerLength; i++)
       {
              // Code to be executed in the outer loop
              for (let j = 0; j < innerLength; j++)
              {
                     // Code to be executed in the inner loop
              }
       }
