Just one operator works with 3 operands. In this first introduction to operators, we'll introduce the operators you are most likely familiar with: operators with 2 operands. Let's now introduce another set of binary operators that you're already familiar with from basic math. If you divide by zero, JavaScript does not raise any error but returns the Infinity value or -Infinity if the value is negative.
A remainder by zero is always NaN , a special value that means "Not a Number":. Every complex statement with multiple operators in the same line will introduce precedence problems.
Some operations have more precedence than the others. The precedence rules are listed in this table:. After assignment and math operators, the third set of operators I want to introduce is conditional operators. Comparison operators always return a boolean, a value that's true or false. In addition to those, we have 4 equality operators.
They accept two values, and return a boolean:. An if statement is used to make the program take a route, or another, depending on the result of an expression evaluation. The conditional checks the expression you pass to it for a true or false value. If you pass a number, that always evaluates to true unless it's 0. If you pass a string, it always evaluates to true unless it's an empty string.
Those are general rules of casting types to a boolean. Did you notice the curly braces? That is called a block , and it is used to group a list of different statements. A block can be put wherever you can have a single statement. And if you have a single statement to execute after the conditionals, you can omit the block, and just write the statement:.
The first is using the array literal syntax. The second uses the Array built-in function. Since we can add an array into an array, we can create multi-dimensional arrays, which have very useful applications e.
You can initialize a new array with a set of values using this syntax, which first initializes an array of 12 elements, and fills each element with the number 0 :. Note that you can set the length of the array.
If you assign a bigger number than the arrays current capacity, nothing happens. If you assign a smaller number, the array is cut at that position:. Returns the first item that returns true, and returns undefined if the element is not found. I personally prefer single quotes all the time, and use double quotes only in HTML to define attributes. Another way to define strings is to use template literals, defined inside backticks.
They are especially useful to make multiline strings much simpler. With single or double quotes you can't define a multiline string easily - you'd need to use escaping characters. Once a template literal is opened with the backtick, you just press enter to create a new line, with no special characters, and it's rendered as-is:. Template literals are also great because they provide an easy way to interpolate variables and expressions into strings.
With a loop we can automate and repeat a block of code however many times we want it to run, even indefinitely. We add a condition after the while keyword, and we provide a block that is run until the condition evaluates to true. Very similar to while , we have do.. It's basically the same as while , except the condition is evaluated after the code block is executed.
We use the for keyword and we pass a set of 3 instructions: the initialization, the condition, and the increment part. Just like with while loops, you can interrupt a for loop using break and you can fast forward to the next iteration of a for loop using continue.
This loop is relatively recent introduced in and it's a simplified version of the for loop:. Note that in the second invokation I passed the black string parameter as the color argument, but no age.
In this case, age inside the function is undefined. Although the conditional will also be true if age is null , 0 or an empty string. You can pass any value as a parameter: numbers, strings, booleans, arrays, objects, and also functions. A function has a return value. By default a function returns undefined , unless you add a return keyword with a value:. They are very often used instead of "regular" functions, the ones I described in the previous chapter.
You'll find both forms used everywhere. If the function body contains just a single statement, you can omit the parentheses and write everything on a single line:.
Arrow functions allow you to have an implicit return - values are returned without having to use the return keyword. Like with regular functions, we can have default values for parameters in case they are not passed:. The two types of functions are very similar, so you might ask why arrow functions were introduced.
The big difference with regular functions is when they are used as object methods. This is something we'll soon look into. Any value that's not of a primitive type a string, a number, a boolean, a symbol, null, or undefined is an object. This is the object literal syntax, which is one of the nicest things in JavaScript. You can also initialize an object using the new keyword before a function with a capital letter. This function serves as a constructor for that object.
In there, we can initialize the arguments we receive as parameters, to setup the initial state of the object:. If you assign a variable the same value of another, if it's a primitive type like a number or a string, they are passed by value:.
Even arrays or functions are, under the hood, objects, so it's very important to understand how they work. The value of a property can be of any type, which means that it can be an array, a function, and it can even be an object, as objects can nest other objects. Here we have a car object with a property named color , with value blue. Labels can be any string, but beware of special characters - if I wanted to include a character not valid as a variable name in the property name, I would have had to use quotes around it:.
The second which is the only one we can use for properties with invalid names , is to use square brackets:. Functions can be assigned to a function property, and in this case they are called methods. Learn facility-based coding by actually working with codes. Numerous and varied examples and exercises within each chapter break chapters into manageable segments and help students gauge learning while reinforcing important concepts Illustrations and examples of key diseases help in understanding how commonly encountered conditions relate to ICDCM coding.
Strong coverage of medical records provides a context for coding and familiarizes students with documents they will encounter on the job. Illustrated, full-color design emphasizes important content such as anatomy and physiology and visually reinforces key concepts. Much diversity and variety among chapters, thus offering broad appeal.

The first quarter of the book is devoted to information theory, including a proof of Shannon's famous Noisy Coding Theorem. The remainder of the book is devoted to coding theory and is independent of the information theory portion of the book.
After a brief discussion of general families of codes, the author discusses linear codes including the Hamming, Golary, the Reed-Muller codes , finite fields, and cyclic codes including the BCH, Reed-Solomon, Justesen, Goppa, and Quadratic Residue codes. An appendix reviews relevant topics from modern algebra. From archiving data, to CD-ROMs, and from coding theory to image analysis, many facets of modern computing rely upon data compression. This book provides a comprehensive reference for the many different types and methods of compression.
Included are a detailed and helpful taxonomy, analysis of most common methods, and discussions on the use and comparative benefits of methods and description of "how to" use them. Detailed descriptions and explanations of the most well-known and frequently used compression methods are covered in a self-contained fashion, with an accessible style and technical level for specialists and non-specialists.
