The ‘use strict’ is a literal expression which is the directive we can add to the code, not in any block. We can add this ‘use strict’ directive in the whole script, a function, or in a class. Syntax ... Read More

If x has the decimal value zero or is a simple integer then it returns x, and if the number is a decimal number (x.yz, here yz is a non-zero number) then it returns x+1. Syntax var x = A.B var value = Math.ceil(x); ... Read More
