![]() ![]() PHP is an open-source server-side scripting language designed for web development by Rasmus Lerdorf. Let’s look at the pros and cons of choosing one over the other: PHP - The Traditional Choice of Developers There has been a burning debate around PHP vs Node.js for a long time. ![]() Both technologies have been a choice of many popular startups and big names in tech because of their robustness, growing community, and modularity. Although PHP has been there longer, Node.js has its own fanbase. PHP and Node.js are two of the most popular backend technologies for modern web development. But before we begin, here’s a quick overview. Today, let’s look into PHP and Node.js and compare it to see which backend technology should you pick for your next project out of two. It takes two parameters, the operands, to be compared for equality and returns a Boolean value indicating whether the operands are equal based on JavaScript strict equality (=).The decision to pick one over the other defines the ease, flexibility, scalability and future of the project. This method is provided under the ng module. The Angular library also provides a method that helps us to determine deep equality between two objects. const assert = require('assert') Ĭonsole.log(epStrictEqual(person1, person2)) //true It will return undefined if the operands are equal and will throw an error if they are not deep and strictly equal. This method will check for strict equality on leaf nodes. The deepStrictEqual() method provided by the assert module is a built-in method in Node.js that takes three parameters: the two operands and a message as an optional parameter that will be used when an error is thrown if the two operands are not equal. Node.js : epStrictEqual(actual, expected, message).Some JavaScript frameworks, such as Angular and Nodejs, provide built-in functionality to determine deep equality in their frameworks. const person1 = ) // true Framework-specific methods Hence, we have to use a recursive method to compare these nested objects.Ī recursive method implementation like the following should be able to tell us whether two given objects are deep equal. But, as mentioned before, these objects can have nested properties. The apparent first thought on anyone’s mind for this problem would be to take each property and compare it against the other operand’s properties and values. However, the following five ways of performing object comparisons make developers’ work easier when a deep equality comparison is required. Referential equality can be determined with equality operators such as strict equality (=) or coercive equality (=) and also by using Object.is() functions, but determining deep equality is tricky as the objects can be nested. Deep equality: Determines whether objects are equal by comparing each property in the operands.Referential equality: Determines whether the two provided operands refer to the same reference/object instance.When discussing object comparisons in JavaScript, there are two types of equalities one must be aware of: In this article, we will discuss five different ways to determine the equality of JavaScript objects. However, comparing non-primitive types such as objects is tricky since the usual equality operators do not compare object values as one might expect. We can compare the values of any of these types using an equality operator. BoldSign – Electronic Signature Software. ![]()
