How to call function from another function using magento knockout js?

Question

I need quick help regarding calling a function within a function using Magento knockout js, I have tried this

define([
    'ko',
    'uiComponent'
], function (ko, Component) {
    'use strict';

    return Component.extend({
        initialize: function () {
            //initialize parent Component
            this._super();
        },

        testfunctionout: function() {
        var self = this;
            console.log(' in testfunctionout');
        self.testfunctionin();
        },

        testfunctionin: function() {
            console.log(' in testfunctionin');
        }

    });
});

Can anyone help me out? Thanks in advance.

 initialize: function () {

 testfunctionout: function() {
        console.log(' in testfunctionout');
    self.testfunctionin();

Try this:

define([
    'ko',
    'uiComponent'
], function (ko, Component) {
    'use strict';

    return Component.extend({
        initialize: function () {
            //initialize parent Component
            var self = this;
            this._super();
        },

        testfunctionout: function() {
            console.log('in testfunctionout');
            this.testfunctionin();
        },

        testfunctionin: function() {
            console.log(' in testfunctionin');
        }

    });
});
