We receive an array of text strings. We need to locate the position of the word "JavaScript" in the array and return its position as an array of two elements: the row index and the column index.

function findWord(matrix, word) {
  let rowIndex = 0;
  let colIndex = 0;
  for (let i = 0; i < matrix.length; i++) { // i = row
    for (let j = 0; j < matrix[i].length; j++) { // j = column
      if (matrix[i][j] === word) {
        rowIndex = i;
        colIndex = j;
      }
    }
  }
  let wordIndex = [rowIndex, colIndex];
  return wordIndex;
}

const data = [
  ['JavaScript', 'Python', 'PHP'],
  ['JavaScript', 'C++', 'Java'],
  ['Python', 'Go', 'C++']
];

findWord(data, 'Java')
