Check if two arrays have the same values

Question

[2,5,3]    

[5,2,3]

They are equal because they have the same values, but not in the same order. Can I find out that without using a foreach loop

Answer 1

I came across this problem and solve it thus: I needed to ensure that two objects had the same fields So

const expectedFields = ['auth', 'message'];
const receivedFields = Object.keys(data);
const everyItemexists = expectedFields.map(i => receivedFields.indexOf(i) > -1);
const condition = everyItemexists.reduce((accumulator, item) => item && accumulator, true);

Basically, go through one of the arrays, here (I'm assuming there are of the same size though). Then check if its exists in the other array. Then i reduce the result of that.
