This crash course is designed for people with no previous experience in programming. By the end of this course you will be able to write simple programs in JavaScript.
First let’s take a look at what JavaScript is. JavaScript is a programming language that is used to create websites. It is a client-side language which means that the code runs in the user’s browser. This makes JavaScript a very powerful tool because it allows you to create dynamic and interactive websites.
Now let’s take a look at some of the basics of JavaScript. In JavaScript, everything is a variable. This means that you can assign a value to any variable. For example, the following code assigns the value “Hello” to the variable name.
var name = “Hello”;
You can also create arrays and objects in JavaScript. Arrays are simply lists of variables, and objects are collections of variables that are associated with each other. Here is an example of an array:
var colors = [“red”, “green”, “blue”];
And here is an example of an object:
var person = {
name: “John”,
age: 30
};
Now let’s take a look at some of the basic commands that you will use in JavaScript. The most basic command is the print command. The print command simply prints the value of a variable to the console. Here is an example:
var name = “John”;
print(name);
This code will print “John” to the console.
The next basic command is the if statement. The if statement allows you to execute code based on a condition. Here is an example:
var age = 30;
if (age > 18) {
print(“You can vote!”);
}
This code will print “You can vote!” if the value of age is greater than 18.
The final basic command that we will look at is the loop. The loop allows you to execute a block of code multiple times. Here is an example:
var colors = [“red”, “green”, “blue”];
for (var i = 0; i < colors.length; i++) { print(colors[i]); } This code will print "red", "green", and "blue" to the console.
