As a beginner in Angular and JavaScript, I am struggling to understand the significance of this particular statement. Can someone please explain its meaning?
messages: string[] = [];
The statement indicates that the specified messages class attribute is limited to containing a collection of string values, and it is being set as an empty array.
An empty array named messages
is being defined and assigned to a variable.
By including the type annotation : string[]
, TypeScript understands that messages
is specifically a list containing strings.

[public|private] varName [:validType] [= someValue]
Here is a breakdown of the different parts:
public message: string = null;
private messages: string[] = [];
