What are ReactiveVars in Meteor and how do I use them?
ReactiveVars are reactive data sources in Meteor that allow you to store and reactively track state. You can create a ReactiveVar using the ReactiveVar constructor.
Can you show me an example of how to create and use a ReactiveVar?
Sure! You can create a ReactiveVar like this: const myVar = new ReactiveVar(initialValue);. To get the value, use myVar.get(), and to set a new value, use myVar.set(newValue).
How do I use ReactiveVars in a template?
In a template, you can use ReactiveVars by calling myVar.get() to display the value and using a helper to update it reactively.
Are there any performance considerations when using ReactiveVars?
Yes, while ReactiveVars are efficient, excessive use can lead to performance issues. It's best to use them judiciously and consider alternatives for large data sets.
