Coding Symbols & Brackets Glossary

Brackets Family

( )

Parentheses

Also: round brackets, parens

Common in function calls, mathematical expressions, and grouping

[ ]

Square Brackets

Also: brackets

Used for arrays, lists, and indexing in most languages

{ }

Code blocks, object literals, scope delimiters

⚠️ NOT "bracers" — that's armor!

< >

Angle Brackets

Also: chevrons

HTML tags, generics (TypeScript, C++), comparison operators

| |

Pipes

Vertical bars

Single: bitwise OR, pipe operator | Double: logical OR || | Context-dependent usage

Quotes & Strings

Double Quotes

Quotation marks

String literals in most languages, allows interpolation in some

Single Quotes

Also: apostrophe

String literals, characters (C/C++), possessives in text

Backtick

Grave accent

Template literals in JavaScript, command substitution in shell

Math & Logic Operators

Plus

Addition operator

Arithmetic addition, string concatenation (some languages)

Minus

Also: hyphen, dash (in text)

Subtraction, negation, hyphen in text/identifiers

Asterisk

Star

Multiplication, pointer dereference (C/C++), wildcard, spread/rest

Slash

Forward slash

Division, path separator, regex delimiter, comments (with another /)

Percent

Modulo operator

Modulo/remainder operation, percentage in text, string formatting

Caret

Circumflex

Bitwise XOR, exponentiation (some languages), regex anchor

Double Asterisk

Exponentiation

Exponentiation operator (Python, JavaScript), power operation

Equals

Assignment operator

Assignment in most languages, equality in some contexts

Double Equals

Equality operator

Equality comparison (loose in JavaScript, coerces types)

===

Triple Equals

Strict equality

Strict equality in JavaScript (checks type and value)

Not Equals

Inequality operator

Not equal comparison (loose in JavaScript)

!==

Strict Not Equals

Strict inequality

Strict inequality in JavaScript (checks type and value)

Logical AND

Double ampersand

Logical AND operator, short-circuit evaluation

Logical OR

Double pipe

Logical OR operator, short-circuit evaluation

Logical NOT

Exclamation mark, bang

Logical negation, boolean NOT, factorial (math), non-null assertion

Ternary Operator

Conditional operator

condition ? trueValue : falseValue — inline conditional

Arrow

Pointer access

Member access via pointer (C/C++), type annotations, transformations

Fat Arrow

Arrow function, lambda

Arrow function in JavaScript/TypeScript, lambda expressions

Delimiters & Punctuation

Colon

Key-value separator (JSON, dicts), type annotations, labels, slice notation

;

Semicolon

Statement terminator (C, Java, JavaScript), command separator

Comma

Separator for parameters, array elements, list items

Dot

Period, point

Member access, decimal point, sentence terminator, wildcard (regex)

...

Ellipsis

Spread/rest operator

Spread syntax (JavaScript), rest parameters, continuation in text

Hash

Pound, number sign, octothorpe

Comments (Python, shell), preprocessor (C), IDs/anchors, private fields

At Sign

Decorators (Python, TypeScript), annotations (Java), email addresses

Underscore

Word separator in identifiers (snake_case), placeholder, private convention

Tilde

Bitwise NOT (C), home directory (Unix), approximation, version ranges

Backslash

Escape character (\n, \t), path separator (Windows), line continuation

Pipe

Vertical bar

Bitwise OR, pipe operator (shell), union types (TypeScript), alternation (regex)

Ampersand

And symbol

Bitwise AND, reference operator (C++), background jobs (shell), HTML entities

Common Phrases & Terms

Opening/Closing Bracket

The left symbol starts (opens) a pair; the right symbol ends (closes) it. Example: ( is opening parenthesis, ) is closing parenthesis.

Brace-Delimited Block

A code block enclosed in curly braces { }. Common in C-style languages for functions, loops, conditionals.

Parenthesized Expression

An expression wrapped in parentheses ( ) for grouping or precedence. Example: (a + b) * c

Angle-Bracket Syntax

Using < > for generics, type parameters, or templates. Example: Array<number>, <div>

Quote-Delimited String

A string literal enclosed in quotes (single, double, or backticks). The quotes delimit (mark the boundaries of) the string content.

Square Bracket Notation

Using [ ] to access array/object elements or define arrays. Example: arr[0], [1, 2, 3]

Important Notes & Pitfalls

⚠️ "Brackets" is Ambiguous

In casual speech, "brackets" can refer to any paired delimiters. Be specific: use "parentheses", "square brackets", "curly braces", or "angle brackets" to avoid confusion.

❌ "Curly Bracers" is WRONG

The correct term is "curly braces" or just "braces". "Bracers" are armor worn on the arms — not programming symbols! This is a common mistake.

ℹ️ Hyphen vs. Minus

In text, - is called a "hyphen" or "dash" (e.g., "multi-line"). In code as an operator, it's "minus" (subtraction or negation). Context matters!

✅ Context is Key

Many symbols have multiple meanings depending on context. * can be multiplication, pointer dereference, or a wildcard. | can be bitwise OR, logical OR, or a pipe operator. Always clarify based on usage.

🌍 Regional Differences

Some terms vary by region. Americans often say "parentheses", while British speakers might say "brackets" for ( ). For global clarity, use the most specific term or provide both names.
