omitIndexes

looking for better implementation

import * as R from 'ramda'

interface OmitIndexes {
  <T>(indexes: number[], arr: T[]): T[]
  (indexes: number[]): <T>(arr: T[]) => T[]
}
export const omitIndexes: OmitIndexes = R.curryN(2, function(
  indexes: number[],
  arr: any[]
) {
  const reject = R.addIndex(R.reject)
  const rejectedIndexes = (_: any, i: any) => R.contains(i, indexes)
  const ret = reject(rejectedIndexes, arr)
  return ret
})

@BjornMelgaard I wouldn’t worry about that. The point of ramda-adjunct is declarativnes and compos-ability. Or main goal is not performance. IMHO for 90% of use-cases ramda-adjunct is just fine. But if you’re building system where performance is the critical factor, I would not recommend to use ramda-adjunct and create use-case based functions with optimized imperative code inside them, so that I get the most performance from JavaScript engine as I possible can.
