+ +This function resolves a [JSON Pointer][json-pointer] reference token against a container, returning the appropriate key. + +
+ + + + + +
+ +## Usage + +```javascript +var resolveToken = require( '@stdlib/utils/json-pointer/base/resolve-token' ); +``` + +#### resolveToken( container, token ) + +Resolves a JSON Pointer reference token against a container. + +```javascript +var obj = { + 'foo': 'bar' +}; +var arr = [ 1, 2, 3 ]; + +var key = resolveToken( obj, 'foo' ); +// returns 'foo' + +key = resolveToken( arr, '0' ); +// returns 0 + +key = resolveToken( arr, '-' ); +// returns 3 +``` + +
+ + + + + +
+ +## Notes + +- For arrays, returns an integer index. +- For arrays, the `-` token is resolved to the array length (`container.length`). +- For objects, returns the token string as-is. +- If `container` is an array and `token` is not a valid array index (or `-`), the function throws an error. + +
+ + + + + +
+ +## Examples + + + +```javascript +var resolveToken = require( '@stdlib/utils/json-pointer/base/resolve-token' ); + +var arr = [ 'apple', 'banana', 'cherry' ]; +var obj = { + 'foo': 'bar', + '0': 'baz' +}; + +var key = resolveToken( arr, '0' ); +console.log( key ); +// => 0 + +key = resolveToken( arr, '2' ); +console.log( key ); +// => 2 + +key = resolveToken( arr, '-' ); +console.log( key ); +// => 3 + +key = resolveToken( obj, 'foo' ); +console.log( key ); +// => 'foo' + +key = resolveToken( obj, '0' ); +console.log( key ); +// => '0' +``` + +
