Setup

let objRedirects = {
  '/foo': '/bar',
  '/a/b/c': '/d/e/f',
  '/xxxxx': '/xxxxx'
}

let mappedRedirects = new Map([
  ['/foo', '/bar'],
  ['/a/b/c', '/d/e/f'],
  ['/xxxxx', '/xxxxx']
])

for (let i = 1; i <= 100; i++){
  objRedirects[`/${i}/${i}/${i}`] = '/value/does/not/matter'
  mappedRedirects.set(`/${i}/${i*10}/${i*100}`,'/value/does/not/matter'
  )
}
