Benchmark: Case insensitive string comparison performance

Script Preparation code:

var u = {
  get a(){
    return "John Doe"
  },
  get b(){
    return "john doe"
  },
  get c(){
    return "john smith"
  }
}

Tests:

toLowerCase() a===b
u.a.toLowerCase() === u.b.toLowerCase()
localeCompare() a===b
u.a.localeCompare(u.b, undefined, { sensitivity: 'base' })
toLowerCase() c===b
u.c.toLowerCase() === u.b.toLowerCase()
localeCompare() c===b
u.c.localeCompare(u.b, undefined, { sensitivity: 'base' })
