first bad version

Question

Say you have multiple versions of a program, write a program that will find and return the first bad revision given a isBad(version) function.

Versions after first bad version are supposed to be all bad versions.

notes

1. Inputs are all non-negative integers
2. if none found, return -1

Code

/*
 type IsBad = (version: number) => boolean
 */

/**
 * @param {IsBad} isBad 
 */
function firstBadVersion(isBad) {
	// firstBadVersion receive a check function isBad
  // and should return a closure which accepts a version number(integer)
  return (version) => {
    // write your code to return the first bad version
    // if none found, return -1
  }
}
