Learning JavaScript: Working with Strings

Strings are the second most common data type used in JavaScript, and in many cases, since JavaScript is so widely used for web applications, it is the prominent data type. In this article I’ll discuss how strings work in JavaScript and how to work with them efficiently and effectively. I’ll also discuss some newer abilities of strings that are just being discovered and used.

Strings Defined

A string is any set of 0 or more characters enclosed in either single quotes or double quotes. The characters in a string can be alphabetic characters, numbers, symbols, and spaces. Here are some examples of JavaScript string literals:

"hello world"
'good bye, world!'
"1600 Pennsylvania Avenue"
'$*&!@ it!'

If you are using single quotes in your string, and you need to embed a single quote to write out a contraction, you use the backslash character (\) as an escape character. To see why you need to do this, let’s look at what happens when you don’t escape a single quote by writing out such a string in the JavaScript shell:

js> 'can't'
typein:1:5 SyntaxError: unexpected token: identifier:
typein:1:5 'can't'
typein:1:5 .....^

The interpreter can’t figure out what to do with the ‘t’ after the single quote.

Now watch what happens when we escape the single quote:

js> 'can\'t'
"can't"

The escape character tells the interpreter to treat the single quote as an apostrophe and not as an “end-of-string” character.

You can embed other characters into a string, including the newline character (\n) and the tab character (\t). Here are some examples using the shell:

js> print("Hello, \n world!");
Hello,
world!
js> print("Hello, \tworld");
Hello,  world

Learning JavaScript: Computing with Object Methods

JavaScript has a set of built-in methods you can use with your user-defined objects. In this article I’m going to discuss several of these methods and how you can use them in your JavaScript programs.

Object.assign

The Object.assign method is used to make a copy of one object into another object. The syntax template for this method is:

Object.assign(target, source);

where source is the object you are copying from and target is the object you are copying into. This method returns the target object if you want to assign it.

Here is a sample program that demonstrates how to use Object.assign:

function Student(name, id, grades) {
  this.name = name;
  this.id = id;
  this.grades = grades;
}
let st1 = new Student("",0,[]);
et st2 = new Student("Jane Doe", 123, [91, 92, 93]);
Object.assign(st1, st2);
print(`${st1.name}, ${st1.id}\n[${st1.grades}]`);

The output from this program is:

Jane Doe, 123
[91, 92, 93]

A good reason to use this method is to make sure that a new object has all the properties and values of the old object. You may accidentally leave something out when writing your own method, while Object.assign will systematically make sure all properties and values are assigned to the new object.

Object.create

The Object.create method creates a new object from an existing object prototype. Here is the syntax template for this method:

const|let|var object-name = Object.create(existing-object);

Let’s look at a few examples to see how this method works in practice. The first example creates a new object from a function and then creates a second object using Object.create:

function Student(name, id, grades) {
  this.name = name;
  this.id = id;
  this.grades = grades;
}
let st1 = new Student("Bob Green", 1234, [81, 77, 92]);
print(`${st1.name}, ${st1.id}\n${st1.grades}`);
let st2 = Object.create(st1);
print(`${st2.name}, ${st2.id}\n${st2.grades}`);

The output from this program is:

Bob Green, 1234
81,77,92
Bob Green, 1234
81,77,92

Code must be written to change the properties of the newly created object.
