how to take the inner product of two vectors code example

Example: product of two vector

let vectors = [[7, 1, 1],[6, 0, 2], [5, 7, 0], [3, 1, 2], [2, 3 ,8], [0, 0, 0]]

function dotProduct(vector1, vector2){
    let result = 0;
    for(let i = 0; i < vector1.length; i++){
        result += vector1[i] * vector2[i]
      }
    return result
  }
  
  for(let i = 0; i < vectors.length; i++){
    for(let j = i + 1; j < vectors.length; j++){
      if(dotProduct(vectors[i], vectors[j]) === 0){
          console.log(`${vectors[i]} and ${vectors[j]} are orthogonal `)
      }
    }
  }
