Determin Highest Value on Array of Objects [duplicate]

Question

I have this problem where the array of objects is intendedly put into this kind of structure:

const productArray = [ { 'Product A': 5000 }, { 'Product B': 2500 }, { 'Product C': 3500 }, { 'Product D': 2750 }, { 'Product E': 1500 }, ];

On what way could I determine the highest and lowest value of this kind of array? Thank you very much.

You're probably better off using a different structure. Either use a single object with different properties, or use an array with the values. Or alternatively an array of objects with both the product name and its value as separate properties. Having an array of objects where every object has a different property is making your own live needlessly hard. — Ivar

@ivar I wish it was the case. But the problem was intendedly put it in this structure. — Shironekomaru

Sort the array, Lowest one will be at first and Largest one will be at last

const productArray = [ { 'Product A': 5000 }, { 'Product B': 2500 }, { 'Product C': 3500 }, { 'Product D': 2750 }, { 'Product E': 1500 }, ]; const sortedProduct = productArray.sort((a, b) => Object.values(a)[0] - Object.values(b)[0]); console.log(sortedProduct); console.log('Lowest value ', sortedProduct[0]); console.log('Highest value ', sortedProduct[sortedProduct.length - 1]);

You can also use Math.max and Math.min.

Thank you so much @andy. I'll try to understand this as this gave a better outcome for my other key:value pair.

No problem. I've updated the fiddle with some comments about how it works, and some links to the relevant documentation. @Shironekomaru

Use find to get the object with that value, and return its first key..

Thanks! There's probably a clever one-liner in there somewhere but I hope the steps I outlined made it easier to understand. @Shironekomaru.
