chore: Refactor price_format function in constant.js

[asimchoudhary]

In current implementation of the price_format function within constant.js . I encountered an issue when the input price does not match the expected pattern. Specifically, the price.match(/.*$([0-9.]+)/) expression returns undefined for inputs that do not contain the pattern. This leads to a subsequent error when attempting to access the length property of undefined in the line if (formatedPrice.length > 0).

appears you're solving for the issue at hand. the below is just a little cleaner. I've tested on my forked version and works fine.

price_format: (price) => {
  const formatedPrice = price.match(/.*\$([0-9.]+)/);
  if (formatedPrice && formatedPrice.length > 0) {
    return parseFloat(formatedPrice[1]);
  }
  return 0.0;
},
