If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23. Find the sum of all the multiples of 3 or 5 below the provided parameter value number.

The project attracts adults and students interested in mathematics and computer programming. Since its creation in 2001 by Colin Hughes, Project Euler has gained notability and popularity worldwide. It includes over 700 problems, with a new one added once every one or two weeks. Problems are of varying difficulty, but each is solvable in less than a minute of CPU time using an efficient algorithm on a modestly powered computer. As of 5 April 2020, Project Euler has more than 1,000,000 users, from all over the world, who have solved at least one problem.

TimeStamps: 00:00 - Challenge 00:34 - Introduction to JSON 01:33 - Processing JSON with Parse and Stringify 03:12 - XMLHTTPRequest 10:38 - Challenge Solution We look into JSON notation and how to process this. Then we look at XMLHttpRequests and how they can be used to obtain JSON data. We open the request and give it properties, call the send method to send it of, and register a function to the onload property to run, once we have a response. Link to Challenge : https://www.freecodecamp.org/learn/data-visualization/json-apis-and-ajax/get-json-with-the-javascript-xmlhttprequest-method Concepts: JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. https://www.json.org/json-en.html parse() The JSON.parse() method parses a JSON string, constructing the JavaScript value or object described by the string. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse stringify() The JSON.stringify() method converts a JavaScript object or value to a JSON string, optionally replacing values if a replacer function is specified or optionally including only the specified properties if a replacer array is specified. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify XMLHttpRequest XMLHttpRequest (XHR) objects are used to interact with servers. You can retrieve data from a URL without having to do a full page refresh. This enables a Web page to update just part of a page without disrupting what the user is doing. XMLHttpRequest is used heavily in AJAX programming. https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest XMLHttpRequest.open() The XMLHttpRequest method open() initializes a newly-created request, or re-initializes an existing one. https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/open XMLHttpRequest.send() The XMLHttpRequest method send() sends the request to the server. If the request is asynchronous (which is the default), this method returns as soon as the request is sent and the result is delivered using events. If the request is synchronous, this method doesn't return until the response has arrived. https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/send XMLHttpRequest.onload The XMLHttpRequestEventTarget.onload is the function called when an XMLHttpRequest transaction completes successfully. https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequestEventTarget/onload XMLHttpRequest.responseText The read-only XMLHttpRequest property responseText returns the text received from a server following a request being sent. https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest/responseText -———————� ... https://www.youtube.com/watch?v=UtPS0WjEnC8

The language has expanded significantly over time, and modern C++ now has object-oriented, generic, and functional features in addition to facilities for low-level memory manipulation. It is almost always implemented as a compiled language, and many vendors provide C++ compilers, including the Free Software Foundation, LLVM, Microsoft, Intel, Oracle, and IBM, so it is available on many platforms. C++ was designed with a bias toward system programming and embedded, resource-constrained software and large systems, with performance, efficiency, and flexibility of use as its design highlights. C++ has also been found useful in many other contexts, with key strengths being software infrastructure and resource-constrained applications, including desktop applications, video games, servers (e.g. e-commerce, Web search, or SQL servers), and performance-critical applications (e.g. telephone switches or space probes).

We can use the D3 attribute method to apply styling properties to SVG elements, including our labels. The style attribute can be used to apply CSS properties. Link to challenge : https://www.freecodecamp.org/learn/data-visualization/data-visualization-with-d3/style-d3-labels Concepts: selection.style(name[, value[, priority]]) If a value is specified, sets the style property with the specified name to the specified value on the selected elements and returns this selection. If the value is a constant, then all elements are given the same style property value; otherwise, if the value is a function, it is evaluated for each selected element, in order, being passed the current datum (d), the current index (i), and the current group (nodes), with this as the current DOM element (nodes[i]). The function’s return value is then used to set each element’s style property. A null value will remove the style property. An optional priority may also be specified, either as null or the string important (without the exclamation point). If a value is not specified, returns the current value of the specified style property for the first (non-null) element in the selection. The current value is defined as the element’s inline value, if present, and otherwise its computed value. Accessing the current style value is generally useful only if you know the selection contains exactly one element. https://github.com/d3/d3-selection/blob/v1.4.1/README.md#selection_style selection.text([value]) If a value is specified, sets the text content to the specified value on all selected elements, replacing any existing child elements. If the value is a constant, then all elements are given the same text content; otherwise, if the value is a function, it is evaluated for each selected element, in order, being passed the current datum (d), the current index (i), and the current group (nodes), with this as the current DOM element (nodes[i]). The function’s return value is then used to set each element’s text content. A null value will clear the content. If a value is not specified, returns the text content for the first (non-null) element in the selection. This is generally useful only if you know the selection contains exactly one element. https://github.com/d3/d3-selection/blob/v1.4.1/README.md#selection_text selection.attr(name[, value]) If a value is specified, sets the attribute with the specified name to the specified value on the selected elements and returns this selection. If the value is a constant, all elements are given the same attribute value; otherwise, if the value is a function, it is evaluated for each selected element, in order, being passed the current datum (d), the current index (i), and the current group (nodes), with this as the current DOM element ... https://www.youtube.com/watch?v=KBI-NIN06d4
