import { drop } from '@opentf/std';
 
drop<T>(
  arr: T[],
  limit: number | null = 1,
  cb?: (val: T) => boolean
)

Examples

drop([1, 2, 3], -1) // It throws the RangeError for negative limit
 
drop([1, 2, 3], 0) // => [1, 2, 3]
 
drop([1, 2, 3]) // => [2, 3]
 
drop([1, 2, 3], 1) // => [2, 3]
 
drop([1, 2, 3], 2) // => [3]
 
drop([1, 2, 3, 4, 5], 5) // => []
 
drop([1, 2, 3, 4, 5], 6) // => []
 
drop([1, 2, 3, 4, 5], null) // => []
 
drop([1, 2, 3, 4, 5], 2, (val) => val % 2 === 0) // => [1, 3, 5]
 
drop([1, 2, 3, 4, 5], 3, (val) => val % 2 !== 0) // => [2, 4]
 
const users = [
  { name: 'x', active: false },
  { name: 'y', active: true },
  { name: 'z', active: false },
];
drop(users, null, (val) => val.active) 
// => [
//   { name: 'x', active: false },
//   { name: 'z', active: false },
// ]
