Use the strict inequality (!==) operator to check if two strings are not equal, e.g. `a !== b`.
You can also use a for...of loop to check if all elements in an array are equal. # Check if all Values in an Array are Equal using a for...of loop This is a three-step process: Use a for...of loop to iterate over the array. Check if each element is not equal to the firs...

Using a Conditional Operator, check if two numbers are equal or not. Challenge Seed function checkEqual(a, b) { } checkEqual(1, 2); Challenge Tests I have not used assert before so correct me if there is an error. There should be a test to check if the camper is actually using a...
The != inequality operator returns false if two values are equal to each other according to == and returns true otherwise. The !== operator returns false if two values are strictly equal to each other and returns true otherwise. As you’ll see in §4.10, the ! operator computes the ...

while the second is an instance of aStringobject. If you place these two values on either side of an equality (==) operator, JavaScript tries various evaluations of the values to see if there is a coincidence somewhere. In this case, the two variable values would show to be equal, and...
We also need to generate the string “return” because when we use the Function constructor, if “return” is not used it is considered a no-op instruction and will not pass our string. To be clear on how to do this without nonalphanumeric code check the following example: alert(Function...
