If x or y is a boolean, convert the other value of a number and compare them.
Similarly, if x is a boolean or string, and y is a number, convert x to a number. If x is a number and y is a string, convert y to a number and then compare using =.If x and y are both either null or undefined, return true.If x and y are of the same type, check if x = y.Here is a brief overview of how the = operator compares if x and y are equal. In Javascript, arrays are considered to be objects, so the = operator only returns true if both the arrays have the same reference // comparing arrays using strict equality If x and y are both objects, it returns true if and only if they reference the same object.If x and y are both booleans, strings, or symbols, then it compares them by value.If x and y are both null or both undefined, it returns true.Otherwise, it also checks to see if they are the same number. If both x and y are either +0 or -0, return true. If x and y are numbers, it checks if either of x or y is NaN, and returns false if one is NaN.If they are of different types, return false. Given 2 values x and y, the strict equality checks for equality in the following way: Before diving into checking for array equality, let us understand how these equality operators work in javascript. Of these, the two most common methods are the = operator, known as abstract equality and the = operator, known as strict equality. There are technically 4 ways to compare if two values are equal in javascript. Checking for array equality using javascriptĮquality is a tricky subject when it comes to javascript.However, If you are here to refresh your knowledge, jump straight to the implementation. If you are new to the concept of array equality, each section of the article would be useful. In this process we will also understand the pros and cons of various methods used. In this article, we cover the different methods to compare two arrays and check if they are equal using javascript. How to check for array equality using Javascript?
