Welcome to the last lesson of this course! Today, we are delving into an essential area of TypeScript territory — the riveting realm of string operations. Broadly speaking, string operations involve manipulating or working with text. In TypeScript, we handle strings much as we do in JavaScript, but with enhanced type safety.
We will navigate through string operations, discover how to concatenate strings and numbers using the + operator, and explore the .concat() method. Strap in and let's traverse the TypeScript terrain!
String operations refer to the various ways in which we can manipulate or interact with strings. Among the simplest and most common is string concatenation. This operation merges separate strings to create a more complex entity. For instance, when we concatenate the strings "Hello " and "World!", they form "Hello World!".
In TypeScript, the + operator serves a dual role — it concatenates and adds, based on the type of input (numbers or strings, respectively). Let's examine an example of using the + operator for concatenation:
