Aug 1, 2020 · 5 min read. __proto__ is a way to inherit properties from an object in JavaScript. __proto__ a property of Object. prototype is an accessor property that exposes the [[Prototype]] of the object through which it is accessed.

Prototypes allow you to easily define methods to all instances of a particular object. The beauty is that the method is applied to the prototype, so it is only stored in the memory once, but every instance of the object has access to it. Let’s use the Pet object that we created in the previous post.

The prototype gives the customer a complete idea of ​​how the site will look like in the final result. Prototyping allows you to streamline the design development process, focusing on important interface elements. Having a prototype in hand, the designer and customer more clearly represent the final result.

__proto__ is the actual object that is used in the lookup chain to resolve methods, etc. The prototype property is only present for functions and is a property that’s set only if you’re using the ‘new’ keyword when creating objects with this (constructor) function.

Prototypes are the mechanism by which JavaScript objects inherit features from one another. In this article, we explain how prototype chains work and look at how the prototype property can be used to add methods to existing constructors.

Define a function named “myFunction”, and make it display “Hello World!” in the

element. Hint: Use the function keyword to define the function (followed by a name, followed by parentheses). Place the code you want executed by the function, inside curly brackets. Then, call the function.

To create a function we can use a function declaration. The function keyword goes first, then goes the name of the function, then a list of parameters between the parentheses (comma-separated, empty in the example above) and finally the code of the function, also named “the function body”, between curly braces.

One method for identifying functions is to look at the difference or the ratio of different values of the dependent variable. For example, if the difference between values of the dependent variable is the same each time we change the independent variable by the same amount, then the function is linear.

Types of Graphs and Charts

• Bar Chart/Graph.
• Pie Chart.
• Line Graph or Chart.
• Histogram Chart.
• Area Chart.
• Dot Graph or Plot.
• Scatter Plot.
• Bubble Chart.

a Bar Graph. Bar graphs are used to compare things between different groups or to track changes over time. However, when trying to measure change over time, bar graphs are best when the changes are larger.

Histograms are useful for displaying continuous data. Bar graphs, line graphs, and histograms have an x- and y-axis.

Histograms are a standard way to graph continuous variables because they show the distribution of the values.

This type of data is often represented using tally charts, bar charts or pie charts. Continuous data is data that can take any value. Height, weight, temperature and length are all examples of continuous data.

Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space. If the data shows pronounced trends or reveals relations between variables, a graph should be used.
