     How to align two elements left and right using tailwind CSS ?
    You can easily float the elements to the left and right using Tailwind CSS. This can be done using either tailwind flex or flow-root classes.

    Classes used:

    • flow-root: This class quickly clears floated content within a container by adding a flow-root utility.
    • position: This is used for controlling the placement of positioned elements.

    This class accepts lots of value in tailwind CSS in which all the properties are covered in class form. This class is used to improving accessibility with screen readers.

    • sr-only: This class is used to hide an element visually without hiding it from screen readers
    • not-sr-only: This class is used to undo the sr-only class effect.

    Difference between double equal vs triple equal JavaScript
    • Double equal: The double equal(‘==’) operator tests for abstract equality i.e. it does the necessary type conversions before doing the equality comparison.
    • Triple equal: The triple equal(‘===’) operator tests for strict equality i.e it will not do the type conversion hence if the two values are not of the same type, when compared, it will return false. 
     What are closures in JavaScript?
    A closure is a feature of JavaScript that allows inner functions to access the outer scope of a function. Closure helps in binding a function to its outer boundary and is created automatically whenever a function is created.
