How to sort an array of objects on the basis of the number value in the object-CodePudding

If I have an array of:

var arr = [{"apple":3}, {"pear":5}, {"orange":1}]

How can I sort this array based on the number value inside the objects desc order?

I want the sorted array to be：

[{"pear":5}, {"apple":3}, {"orange":1}]

CodePudding user response：

Try this.

const newArr = arr.sort((a, b) => {
return Object.values(b)[0] -  Object.values(a)[0];
});

CodePudding user response：

You need to create another variable, then run the array variable with .reverse(); at the end.

Just a reference for you,waiting for more elegant solution to it

var arr = [{"apple":3}, {"pear":5}, {"orange":1}]
arr.sort((a,b)=>{
  //return b[Object.keys(b)[0]] - a[Object.keys(a)[0]]
  return Object.values(b)[0] -  Object.values(a)[0];
})

console.log(arr)
