How can I find the index of a 2d array of objects in JavaScript?

To find the index of a two-dimensional array of objects, use two for loops, one for row and another for column. Following is the code −

Example

function matrixIndexed(details, name) {    var r;    var c;    for (r = 0; r < details.length; ++r) {       const nsDetails = details[r];       for (c = 0; c < nsDetails.length; ++c) {          const tempObject = nsDetails[c];          if (tempObject.studentName === name) {             return { r, c};          }       }    }    return {}; } const details = [    [       {studentName: 'John'}, {studentName:'David'}    ],    [       {studentName:"Mike"},{studentName:'Bob'},{studentName:'Carol'}    ] ]; var {r, c } = matrixIndexed(details, 'Bob'); console.log(r, c);

To run the above program, you need to use the following command −

node fileName.js.

Output

Here, my file name is demo160.js. This will produce the following output −
