You may already be familiar with the equals and strict equals operators in JavaScript. The equals operator (==) checks if two items are equal in value. The strict equals operator (===) checks if they’re both equal in value and in type. // returns true /
A) The first was to divide the array in equal chunks, for example chunks of 2 or 3 items B) The second was to create n chunks and add an equal variable set of items to itIt’s different how and why we divide. Solution (A) is great when you don’t know how many groups you’...

The assert.deepStrictEqual() method tests if two objects, and their child objects, are equal, using the === operator.If the two objects are not equal, an assertion failure is being caused, and the program is terminated.The === operator tests if the values and the types are equal....
If it is, the method returnstrue, otherwise,falseis returned. I wrotea bookin which I share everything I know about how to become a better, more efficient programmer. You can use the search field on myHome Pageto filter through all of my articles. ...
ThestrictEqual()assertion provides the most rigid comparison of type and value with the strict equality operator (===). assert.equal()can be used to test non-strict equality. assert.notStrictEqual()can be used to explicitly test strict inequality. ...
to the same memory address. This is often used when checking if two variables are the same instance of an object. If two variables have referential equality, any change made to one of them will also affect the other. In JavaScript, referential equality can be checked using the===operator....
The equal assertion uses the simple comparison operator (==) to compare the actual and expected arguments. When they are equal, the assertion passes; otherwise, it fails. When it fails, both actual and expected values are displayed in the test result, in addition to a given message....
