How to convert pages in main.js file to pages object in app.json

use javascript to convert ["pages/logs/main"," ^ pages/index/main", "pages/counter/main"] to
[
    "pages/index/main",
    "pages/counter/main",
    "pages/logs/main"
]

description: raise the item ^ pages/index/main to the front of the array and remove ^

var pages =["pages/logs/main", "^pages/index/main", "pages/counter/main"] 
var startPageIndex = pages.findIndex(v => { return v[0] === "^"})
var startPage = pages[headIndex].slice(1)
pages.splice(startPageIndex, 1)
pages.unshift(startPage)
console.log(pages)

is there a more streamlined operation than this, gods?
