# Check if a Variable is False in JavaScript Use the strict equality (===) operator to check if a variable is equal to false. The strict equality (===) operator will return true if the variable is equal to false, otherwise, it will return false. index.js const a = false; // ✅...
For example, if the value of an object key is an array, or another object, thestrict equalsoperator we use in our loop will alwaysreturn false. To get around this, we can use a technique calledrecursion. Rather than usingstrict equalsinside theareArraysEqual()andareObjectsEqual()functions,...

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....
This is why the conditionif (a != null)evaluates totrueifais not equal tonullandundefined. This is the most common use case for the loose equality (==, !==) operators in JavaScript. If you use the loose equality operator to check if two values are not equal, you might get confusing...
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....

The strictEqual() 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....
