Why is the raisePropertyChanged Event important in programming?

I was confused about the purpose of this particular event based on the official documentation.

This event is commonly utilized in developing controls with client-side support (IScriptControl).

 get_highlightCssClass: function() {
        return this._highlightCssClass;
    },

    set_highlightCssClass: function(value) {
        if (this._highlightCssClass !== value) {
            this._highlightCssClass = value;
            this.raisePropertyChanged('highlightCssClass');
        }
    },

Is it intended to update a server-side property from the client side?
How can I capture this event on the server side and retrieve the updated property value?
