test() method: Regular Expression - Course JavaScript - Part 9 | web Developer courses

In this video we start our discussion of regular expressions. Regular expressions are coded patterns that can be used to search for matching patterns in strings.

Course:  

Duration:  15 minutes

Summary: In this video we start our discussion of regular expressions. Regular expressions are coded patterns that can be used to search for matching patterns in strings. We start by creating a string and a regular expression to test for. We used the test() method for that purpose. We showed couple of ways to create the regular expression: first using the RegExp() constructor, second using the // and the pattern exists inside the forward slashes. We also used the ‘i’ after the last slash to signify ‘ignore case’. In the second example, we created a function to match a specific pattern, but in this case using ‘g’ and a while loop to do a global search and find all the matches in the string. Finally, we added a new function br() to add a break to the screen instead of always writing ‘document.writeln(“
”);’

Methodology of the development of example: Good coding standard and simplified design.

Technology Used: JavaScript – Core language Concepts

Keywords: JavaScript, HTML, function, var, script, document, writeln, Regular Expression, pattern, RegExp, test, exec, ignoreCase.
