Length and concat: The String Object - Course JavaScript - Part 7 | web Developer courses

Duration:  15 minutes

Summary: In this video we start our discussion of the String object. As I mentioned in the previous video, JavaScript supports object-oriented concepts. In addition to the Number object (discussed in the previous video), we talk about the String class. JavaScript has very powerful string functionality. We will see here to create a String instance and call some string functions. Some of the functions are strictly related to strings (such as length and concat), others are related to the use of JavaScript with HTML. You will see how to display blinking strings and strings in italics, bold, big, small, sup, and strike. We will also see how to create a link using a string instead of using the tag from HTML. There are other String functions that we will discuss in the next video. You will see the power of these functions as we create more examples in the upcoming videos.

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