I have successfully created a 4-dimensional array in JavaScript. One of the columns consists of String values, while the other three columns contain float values. I populated the first three columns using data from a JSON response, and for the fourth column, I calculated the magnitude based on the values in columns 2 and 3. Now, my task is to sort the entire array based on the values in column 4. Below is the code snippet that demonstrates how I initialized and filled the array. Could someone kindly guide me on how to implement sorting based on column 4?
var labels = responseJSON.labels;
var knowledge = responseJSON.knowledge;
var interest = responseJSON.interest;
var label_know_int_array = new Array(4);
//array item 0 holds all the labels
label_know_int_array[0] = new Array(200);
//array item 1 stores knowledge values
label_know_int_array[1] = new Array(200);
//array item 2 saves interest values
label_know_int_array[2] = new Array(200);
//array item 3 calculates the magnitude of knowledge and interest
label_know_int_array[3] = new Array(200);
for(var i=0;i<labels.length;i++)
{
label_know_int_array[0][i] = labels[i];
var knowVal = knowledge[i];
var intVal = interest[i];
label_know_int_array[1][i] = knowVal;
label_know_int_array[2][i] = intVal ;
var squareSum = (knowVal*knowVal) + (intVal*intVal);
var distance = Math.sqrt(squareSum);
label_know_int_array[3][i] = distance ;
}
