# JavaScript: Convert the values of RGB components to a color code

## JavaScript fundamental (ES6 Syntax): Exercise-252 with Solution

Write a JavaScript program to convert the values of RGB components to a color code.

• Convert given RGB parameters to hexadecimal string using bitwise left-shift operator (<<) and Number.prototype.toString(16).
• Use String.prototype.padStart(6, '0') to get a 6-digit hexadecimal value.

Sample Solution:

JavaScript Code:

``````//#Source https://bit.ly/2neWfJ2
// Define a function 'RGBToHex' to convert RGB values to hexadecimal format
const RGBToHex = (r, g, b) =>
// Combine the RGB values into a single number, convert it to hexadecimal,
// and pad the result with zeros to ensure it has 6 digits
((r << 16) + (g << 8) + b).toString(16).padStart(6, '0');

// Test the 'RGBToHex' function with sample RGB values
console.log(RGBToHex(255, 165, 1)); // Output: "ffa501"
console.log(RGBToHex(255, 255, 1)); // Output: "ffff01"
```
```

Output:

```ffa501
ffff01
```
