How Do I Find the Largest Number in a 3D JavaScript Array?
Let’s say the following is our array;
var theValuesIn3DArray = [75, [18, 89], [56, [97], [99]]];
Use the concept of flat() within the Math.max() to get the largest number.
Example
var theValuesIn3DArray = [75, [18, 89], [56, [97], [99]]];
Array.prototype.findTheLargestNumberIn3dArray = function (){
return Math.max(...this.flat(Infinity));
}
console.log("The largest number in 3D array is=");
console.log(theValuesIn3DArray.findTheLargestNumberIn3dArray());To run the above program, you need to use the following command −
node fileName.js.
Here, my file name is demo202.js.
Output
This will produce the following output −
PS C:\Users\Amit\javascript-code> node demo202.js The largest number in 3D array is= 99
