“Knowledge is power.” – Francis Bacon

Rust supports standard operators for arithmetic (+, –, *, /), comparison (==, !=, <, >), and logic (&&, ||, !). These operators work on numbers, booleans, and some custom types, making them essential for performing calculations and decisions in your code. In this post, I will explain how to use operators in Rust. If you […]

Rust has two main string types: &str (a string slice) and String (a growable, heap-allocated string). &str is usually used for static or borrowed strings, while String is used when you need to modify or own the string data. In JavaScript, you often work with strings directly, and most of the time you do not

Rust has four main categories of scalar primitive types: integers, floating-point numbers, booleans, and characters. These types are built into the language, fixed in size, and form the foundation of all value handling in Rust programs. To write useful programs in Rust, you need to work with basic values like numbers, text, and true-or-false conditions.

In Rust, variable shadowing lets you reuse the same variable name in the same or a nested scope. Each shadowed variable is a new binding, which allows transformations or type changes without using a new name. When learning how Rust handles variables, one powerful feature to understand is shadowing. This lets you declare a variable

Rust is a statically typed language, which means every variable must have a type known at compile time. You can either write this type explicitly using type annotations, or let Rust figure it out automatically using type inference. Rust aims to make your code safe without making you write more than necessary. When you write

In Rust, constants are defined using const and must have a fixed type and value known at compile time. Unlike mutable variables, constants never change and can be used throughout your code wherever needed. Use const for values like limits, defaults, or settings that should stay the same. Once you understand how variables work in

In Rust, variables are declared using let. By default, all variables are immutable, which means you cannot change their values. To make a variable mutable, add mut like this: let mut x = 5. This is different from JavaScript, where variables are often mutable by default. When you begin writing real programs in Rust, you

To write your first Rust program, use cargo new project_name, then open main.rs and add a main function with a println! macro. This prints a message to the terminal. Rust programs always start from the main function. Once your Rust environment is set up, the next step is to write and understand your first program.

To set up Rust on your computer, install Rust using rustup, which includes the compiler (rustc) and build tool (cargo). Use cargo new to create your first project, and run it with cargo run. For the best experience, use Visual Studio Code with the rust-analyzer extension. If you are ready to start coding in Rust,

Rust is a fast, safe, modern programming language that compiles to native code and helps prevent bugs through strict compile-time checks. It is ideal for JavaScript developers who want more control, better performance, and safer concurrency in system-level or backend development. If you are a JavaScript developer and you are wondering what Rust is and
