Well arrays are in a way objects with ordered and enumerated property names and length property. 1. If you've a JSON format set, like a particular API endpoint returning JSON, and you want to compare the same structure for a possible change in values, you can directly convert both payl. If the current element is array (muti-dimensional) then recursively check its elements with the corresponding element. If you feel like "Fuck it", then you can just do JSON.stringify (a)===JSON.stringify (b); but this will fail under some circumstances, and yield false positive results. JavaScript arrays are a special type of objects, and just like regular objects, comparison of two arrays will return false even when they contain the same elements: Comparing Arrays with Arrays.equals So far we only compared arrays based on their object identities. If nothing happens, download GitHub Desktop and try again. Comparing Arrays with Arrays.equals So far we only compared arrays based on their object identities. Two arrays are considered to be equal if their length, each element in both arrays are equal and in the same order to one another.
