This is the root of the vaunted “Unix Philosophy:” Write small utilities and scripts that compose well. this can be additionally the JavaScript philosophy: Make small issues that may be mixed and recombined to enlarge things.

Programming with items will be performed during this sort, and JavaScript makes it rather effortless to mix and recombine small components. sessions could be equipped from features rather than from superclasses. items can delegate and ahead behaviour to helpers and meta-objects. Adaptors could be written to alter an object’s interface while not having to create one other classification in a hierarchy.

JavaScript Spessore is a booklet that describes this method of operating with gadgets and metaobjects in JavaScript. It’s the exact same philosophy as you discover in JavaScript Allongé, basically it talks to programming with gadgets rather than programming with functions.

If you place the increment operator after a variable, such as: var somenumber = 10 var someothernumber someothernumber = somenumber++ The assignment operation will take place before the evaluation operation. In other words, first someothernumber will be set equal to the value of somenumber, then the value of somenumber will be incremented. In our example, that means that someothernumber will equal 10 and somenumber will equal 11. If you wish to rewrite the statement so that the increment takes place first, just reposition the increment sign: someothernumber = ++somenumber JavaScript Fundamentals n 33 In this case, somenumber is incremented to 11 and then that value is assigned to someothernumber.

The values of such objects’ properties are usually read-only. A static object is a single object, and thus does not enable you to create instances of it. For example, the Math object in JavaScript is a static one, because you cannot create instances according to its template. Its methods are common mathematical functions, whereas its properties are mostly mathematical constants. n Dynamic objects—objects by which instances are created. A dynamic object resembles a template. You do not touch or use the object directly.
