Compare text of equal strings in JavaScript [duplicate]

Question

I have a little problem to solve. I want to compare two texts if they are the same.

let currentValue = "24960307.W 25880305.W 24880208.W 25650156.W"

let newValue = "24880208.W 24960307.W 25650156.W 25880305.W"

// is the same text just diferent order

// when i did includes 
let x = currentValue.includes(value);
console.log(x);


//response in console
false

I tried with includes and localeCompare but still show that text is different.

They are different. How exactly are they supposed to be compared? What’s the rule? — Sebastian Simon

What's value in that code? I mean... you have to check each part of the two strings if order is not important and you're stuck with string representation. This isn't the same text, but may be the same value for your purposes. — Dave Newton

With "is the same text just diferent [sic] order" are you referring to the different parts of the strings? I think you want to split the strings on, say, a space, and compare the arrays. — Heretic Monkey

A quick solution to normalize order is to split, sort, rejoin, then compare. This avoids any fancy parsing.

let currentValue = "24960307.W 25880305.W 24880208.W 25650156.W"
let newValue = "25880305.W 24880208.W 25650156.W 24960307.W"


const a = currentValue.split(' ').sort().join(' ')
const b = newValue.split(' ').sort().join(' ')

console.log(a === b)

let x = a.localeCompare(b) === 0
console.log(x);
