str-indexes-of

Like String#indexOf(), but return all indexes instead of the first one

import strIndexesOf from 'str-indexes-of';

strIndexesOf('aaa', 'a'); //=> [0, 1, 2]
strIndexesOf('ffoofffofofofofofffooffoo', 'foo'); //=> [1, 18, 22]

Almost the same module as indexes-of, but:

• only supports String explicitly
  • throws TypeError when it takes an Array
• supports optional fromIndex parameter
• disallows empty search value

Installation

Use npm.

npm install str-indexes-of

API

import strIndexesOf from 'str-indexes-of';

strIndexesOf(str, searchValue [, fromIndex])

str: string
searchValue: string (value to search for)
fromIndex: number (index in the string where to begin searching)
Return: Array of string

strIndexesOf('ABC-ABC', 'A'); //=> [0, 4]
strIndexesOf('ABC-ABC', 'A', 4); //=> [4]
