What are Brackets?

In coding, brackets are like special symbols which combine with similar code parts. They help organize the code, make it easier to understand, and allow it to change quickly.

4 Types of Brackets in Coding

There are four types of brackets in coding:

Round brackets, also known as parentheses; curly brackets, also known as braces; square brackets; angle brackets are chevrons or less than/greater than signs.

Each type of bracket in coding has its own rules and way of using it, and they all have different purposes. Knowing how to use them correctly is essential to make your code easy to read and organize.

Round Brackets

The most commonly used type of bracket in coding is called round brackets, also called parentheses. They are group expressions that show that a function calls and gives information to a position. In most programming languages, you use parentheses when you want to call a function.

For instance, if you’re using JavaScript and you want to call a function called “add” with two numbers, you would write “add(3, 5)” using parentheses to show that you’re calling the process and enclosing the numbers.

round bracket

Parentheses are to indicate precedence in mathematical expressions. For example, in the face (3 + 5) * 2, the parentheses indicate that the addition operation should be performed first, followed by multiplication. Parentheses can also be used to group expressions, such as (a + b) * (c + d), to indicate the order of operations.

Curly Brackets

Curly brackets, also known as braces, indicate the beginning and end of a code block. They are commonly in loops, functions, conditional statements, and object literals. For example, in JavaScript, the syntax for creating a process is:

curly brackets

function myFunction() {
//code goes here

The curly brackets indicate the beginning and end of the function and the code that should be executed when the function is called. Curly brackets can create object literals, a data structure allowing storing multiple values in a single variable. For example, in JavaScript, the syntax for creating an object literal is:

let myObject = {
key1: value1,
key2: value2,
key3: value3

The curly brackets indicate the beginning and end of the object literal, and commas separate the key-value pairs.

Square Brackets

In coding, using square brackets signifies an array’s presence. These arrays are a crucial data structure in programming that allows storing multiple values within one variable. In JavaScript, a collection creates a specific syntax that involves square brackets.

square brackets

let myArray = [value1, value2, value3];

The square brackets indicate the beginning and end of the array, and commas separate the values. Square brackets access elements in an array or object.

For example, in JavaScript, the syntax for accessing the first element of an array is:


The square brackets indicate the index of the element to access.

Angle Brackets

Angle brackets, also known as chevrons or less than/greater than signs, are in several programming languages to indicate the beginning and end of a template. Templates are in generic programming to define a generic type or function that can work with multiple classes.

angle brackets

For example, in C++, the syntax for creating a vector of integers is:


The angle brackets indicate the template; the type parameter encloses in parentheses. Angle brackets are in HTML to show tags.

For example, the syntax for creating a hyperlink in HTML is:

<a href="http://example.com">Link</a>

The angle brackets indicate the beginning and end of the hyperlink tag.

What do round brackets and brackets () in coding represent?

In mathematical calculations, round brackets are mainly used to enclose function arguments. Additionally, they are used for group expressions and regulate the sequence of operations.

What do square brackets in coding represent?

Square brackets are frequently used to access specific characters in strings, index elements in arrays or lists. Moreover, it is used while working with data slices.

What are the coding applications for curly brackets or braces?

Code blocks, such as loops (for, while) and conditional statements (if, else), are frequently defined using curly brackets. In some programming languages, like JavaScript, they are also essential for defining objects.

Do any programming languages utilize a single kind of bracket?

Using brackets (round brackets) for all types of expressions and control structures is common in some programming languages, such as Lisp.

What should I do if my code contains brackets that don't match?

Syntax mistakes can result from mismatched brackets in your code. To fix this problem, carefully review your code to identify any missing or extra frames, then make the required adjustments.

How can I keep my code's indentation and bracket balance consistent for better readability?

For code to be readable, consistent indentation and appropriate bracket usage are necessary. Most contemporary code editors and integrated development environments (IDEs) can assist you in automatically formatting your code. Including proper bracket alignment, making it simpler to maintain bracket balance and enhancing code readability.


Using brackets in coding is crucial in organizing and clarifying the structure of your code. This article has explored the various types of frames utilized in programming, including round, curly, square, and angle brackets. Each class follows specific rules and conventions; comprehending their usage is vital for writing clean, well-structured codes.

By using brackets correctly, you can enhance the readability and maintainability of your code, simplifying debugging and modifications. Whether you’re a novice or a seasoned programmer, understanding the different bracket types and their usage is beneficial for improving coding abilities and productivity.

In summary, brackets are a critical coding component, aiding in organizing and structuring code. Whether working on a small project or a complex application, mastering bracket usage can assist you in creating clean, well-organized, and maintainable code. Therefore, investing time in learning and practicing the use of various bracket types in coding is fundamental to becoming a skilled and efficient programmer.

Thus this was all about types of brackets in coding.
