Now that we have discussed how to create an observable from a sequence, let's see how we can create an observable from a sequence factory. RxJS has a built-in method called generate() that lets you create an observable from an iteration (such as a for() loop). This method has the following signature:
Rx.Observable.generate(initialState, conditionFunction, iterationFunction, resultFactory, [scheduler]);
In this method, the only optional parameter is the last one. A brief description of all the parameters is as follows:
- initialState: This can be any object, it is the first object used in the iteration
- conditionFunction: This is a function with the condition to stop the iteration
- iterationFunction ...
