The Different Parts of JavaScript

JavaScript Syntax

In computer programming, syntax refers to the rules that govern the structure of a program. This can include the order of declarations, how functions are invoked, and other elements that determine how code is written. In JavaScript, syntax is relatively simple and consistent compared to other popular programming languages. This makes it a good choice for beginners who are just learning to code.

JavaScript syntax can be divided into three main parts:

– Comments: These are lines of code that are not executed by the program, but are instead used to leave notes for other programmers (or for yourself). Comments start with // or /* and end with */.
– Declarations: These lines of code create variables and functions. Variables store data values (like numbers or strings) that can be used later in the program. Functions are reusable blocks of code that perform a specific task.
– Statements & Expressions: Statements are incomplete lines of code that must be combined with expressions to form a complete instruction. Expressions are complete instructions that can be executed on their own.

JavaScript Objects

An object is a collection of related data and/or functionality. In JavaScript, an object is a standalone entity, with properties and type. You can define an object by using an object literal:

var myObject = {
type: ‘JS Object’,
params: [‘collections’, ‘of’, ‘related’, ‘data’]
An Object Literal is a comma-separated list of name-value pairs wrapped in curly braces. In the example above, the object myObject has two properties: type and params. The data inside an object is called a property. Objects can contain many properties, and the data inside those properties can be any data type — strings, numbers, booleans, arrays, functions, or even other objects.

You access the values inside an object by using dot notation or bracket notation:

console.log(myObject.type); // returns JS Object
console.log(myObject[‘params’]); // returns [‘collections’, ‘of’, ‘related’, ‘data’]

JavaScript Functions

A function is a set of instructions that can be run over and over again. A function takes input, does something with that input, and then gives an output. In JS, we use the keyword function to create a function.

Let’s say we want to create a function that takes a name as input and prints out “Hello, ____!” We would write it like this:

function sayHello(name) {
console.log(“Hello, “ + name + “!”);

This function takes in one parameter — name — and prints out a hello message using that parameter. Notice that the parameter is put inside the parentheses after the function name. Also notice that there is only one parameter in this example, but you can have multiple parameters separated by commas inside the parentheses.

To actually run this function, or to “call” it, we need to put parentheses after the function name and pass in an argument — in this case, a string with a name:

sayHello(“Tyler”); // prints out “Hello Tyler!”

How Long Does It Take to Learn the Different Parts of JavaScript?

JavaScript has been around for a while, and it is still one of the most popular programming languages. It is a versatile language that can be used for front-end development, back-end development, and everything in between. So, how long does it take to learn JavaScript?

JavaScript Syntax

JavaScript syntax is the set of rules that define a correctly structured JavaScript program. It’s important to have a good understanding of syntax because it can make the difference between code that runs and code that doesn’t.

The good news is that JavaScript syntax is relatively simple compared to other programming languages. In fact, it’s often said that once you learn the basics of JavaScript, the rest is just functions and objects.

Assuming you already have a basic understanding of programming, here’s a rough estimate of how long it would take to learn the different parts of JavaScript syntax:

-Basic Syntax: 1-2 weeks
-Functions: 2-3 weeks
-Objects: 3-4 weeks

JavaScript Objects

JavaScript objects are containers for named values called properties or methods. A JavaScript object has a property named by an identifier. Values can be of any type, including other objects. To create an object, you use code like this:

var obj = new Object();

The keyword “new” creates the object. The keyword “var” assigns the object to a variable named “obj.” You can refer to the properties of an object by name, using either dot notation: = “Chuck”;

or bracket notation:

obj[“name”] = “Chuck”;

You can create objects with your own custom properties and values. You assign values to custom properties just like you would assign values to the predefined properties of a built-in object, such as Array or Date.

JavaScript Functions

JavaScript functions are one of the most important aspects of the language. A function is a self-contained piece of code that can be executed by a JavaScript interpreter. Functions can take arguments and return values. They can be used to create objects and modify data.

Functions are declared with the function keyword, followed by a name and parentheses. The function keyword is optional in JavaScript, but it is generally used to make code more readable. Functions can be defined in a number of ways, including inline, in a script, or in an external file.

Inline functions are defined within a script tag, in the element of an HTML document, or within another function. Inline functions are convenient for small pieces of code that will be executed only once.

Script-level functions are defined within a
