The JavaScript, thevoidoperator is used to explicitly return undefined. Its a unary operator, meaning only one operand can be used with it. You can use it like shown below — standalone or with a parenthesis. voidexpression;void(expression); Lets see some examples void0;//returns undefi...
Unclear browser API is not the only problem in JavaScript related to NaN. As you also may know, NaN as an operand transforms any arithmetic operation result into NaN: Copy >1+NaNNaN Plus, NaN does not equal anything, even itself: Copy >false==NaNfalse>NaN!=NaNtrue Such behavior is so ...

In JavaScript, a nullish value is a value that is: null, or; undefined. Nullsih values are always falsy. For example, the nullish coalescing operator (??) returns its right-hand side operand when its left-hand side operand is a nullish value, and returns its left-hand side operand ...
Then we move out toseven(add). Based on the same function as before, we see that this time a function was indeed passed in. Therefore, the return value is the function addinvoked, with the number7passed in. Finally, add executes using the remembered value of5from its outer scope, and...

Unary operators work with only one operand. An example is the negation operator "-", which can change a positive number to negative. Binary operators, on the other hand, require two operands. An example would be the addition operator "+", which adds two numbers together. ...
Notice that in this example script: A function is defined with a "function" statement and named as "square". The function is called to execute as an operand in an expression in its name. One input value is passed into the function at the calling time. ...
It ensures each boolean operand (such as conditions within if or while statements) is tested for both true and false values, improving test completeness.Condition Coverage (%) = (Number of executed Operands) / (Total number of operands) * 100 Loop Coverage: This metric ensures each loop in ...
Using Javascript’s void(0), you can show a page won’t refresh or load when a link is clicked. We can use the operand 0 in two ways that are void(0) or void 0. Both of these methods are the same. The JavaScript function:void(0) tells the browser not to do anything, i.e.,...
