Understand the difference between Javascript "==" and "===" operators:
In JavaScript, "==" is the equality operator and "===" is the strict equality operator.
The main difference between the two is that "==" compares values for equality and performs type coercion if necessary, while "===" compares both values and types for equality.
For example:
If you use "==" to compare the number 5 to the string "5", the comparison will return true because JavaScript will transform the string to a number before performing the comparison.
However, if you compare the same values using "===", the comparison will fail since the string's type is not the same as the number's type.
In general, using "===" is considered best practice since it is less prone to unexpected behavior caused by type coercion.
As you can see, "==" will resort to type coercion if necessary to assess the comparison, whereas "===" won't.
In the absence of knowledge of the type of coercion that "==" executes, unexpected results can be produced.
Using "===" is a best practice to avoid such complications
In CSS, absolute positioning is a way to position an element relative to its nearest positioned ancestor element rather than to the viewport or the normal flow of the document.
To use absolute positioning, you first need to set the position property of an ancestor element to a value other than "static", such as "relative" or "absolute".
