How to Compare Two JavaScrpt Arrays
This tutorial will show you some ways of comparing two arrays.
The JSON.stringify() method
The toString() Method
You can also invoke toString() for camparing an array of numbers and string:
The Array.prototype.every() Method
An alternate way of the above solution is Array.prototype.every() to compare each element of the array with the elements of another array:
Arrays are list-like objects, and their elements are properties with names 0, 1, 2 .. etc. They have special properties: length and many functions that manipulate the elements. Neither the length nor the types of the elements are fixed.
The arrays are zero-indexed, meaning that the first element is at index 0, and the index of the last element is equivalent to the value of the length property minus 1.
