JavaScript functions can be defined in a number of ways, such as function expressions, arrow functions, or the function keyword. The following is the syntax ... Read More

CDATA, the short form of Character Data is a block of code that has been written to prevent parsing by the parser. Sometimes our data includes predefined characters like “ Syntax str.replace("regex", "") Here str is the string from which you want to remove the CDATA, regex is the regular expression to find the block data. Example In the below program example, we remove the CDATA blocks and tags inside a script element using the String replace() method.

It returns a Boolean value, which depends on the truthiness of the expression.  How It Works: The first ! negates the value, converting it to true or false. The second ! negates it again, effectively converting it into a strict boolean (true or ... Read More
