How can I format numbers in JavaScript to display a minimum number of decimal places?

Formatting Numbers in JavaScript

Regarding your query on formatting numbers in JavaScript, you can leverage the built-in function toLocaleString() with the minimumFractionDigits option.

The toLocaleString() method enables you to format numbers based on the user's locale settings or a specified locale. By setting minimumFractionDigits to a specific value, you can control the minimum number of digits displayed after the decimal point.

For instance, to format a number with a minimum of two decimal places:

<code class="js">var value = (100000).toLocaleString(
  undefined, // leave undefined to use the visitor's browser locale
  { minimumFractionDigits: 2 }
);
console.log(value); // Output: "100,000.00"</code>

It's worth noting that support for extended toLocaleString() options can vary across browsers. If you're using Node.js, you may need to install the intl package via npm.
