Did you know that each website and online resource has a unique URL for its address? Uniform Resource Locators, or URLs, can appear straightforward but contain numerous components and special characters, making them truly fairly complex.
Built-in JavaScript Encoding Functions
When It comes to encoding in JavaScript. It Gives to two functions to perform encoding encodeURIComponent() and encodeURI().
How to use encodeURI in JavaScript
This function is used for encoding the complete URI (Uniform Resource Identifier). A limitation of we can say feature of encodeURI is that it does not encode characters ~!@#$&*()=:/,;?+' .
Syntax:
const originalURI = "https://www.dev.to/search?q=Hello dev";
const encodedURI = encodeURI(originalURI);
console.log(encodedURI);
VM249:3 https://www.dev.to/search?q=Hello%20dev
How to use encodeURIComponent in JavaScript
This function is used to encode complete URL (Uniform Resource Locator) instead of URI.
Syntax:
const originalURI = "https://www.dev.to/search?q=Hello dev";
const encodedURI = encodeURIComponent(originalURI);
console.log(encodedURI);
VM261:3 https%3A%2F%2Fwww.dev.to%2Fsearch%3Fq%3DHello%20dev
You can use any online JavaScript code executor, browser console, or online URL encoder tool to verify your encoding output.
Encoding vs Encryption
People frequently get confused between encoding and encryption. Although both are used to transform data but to serve different purposes and requirements.
Encoding: Encoding is used to transform data into specific format without maintaining security. It is easily reversible using appropriate method.
Encryption:: Encryption is used to protect data using complex algorithms. It ensures data confidentiality and security. Encrypted data is also reversible but only with the correct decryption key.
