array-back
Advanced tools
The array-back npm package is designed to ensure that any value provided to it is returned as an array. This can be useful when you are not sure if a function will receive an argument as a single value or an array of values. It helps to normalize the input for further processing.
Convert a non-array value to an array
This feature takes a single value and wraps it in an array. If the value is already an array, it returns the array unchanged.
[].concat(arrayBack(value))
Flatten nested arrays
This feature can be used to flatten nested arrays into a single-level array.
arrayBack([1, [2, [3]]])
Ignore empty slots in sparse arrays
This feature allows the conversion of sparse arrays into compact arrays without empty slots.
arrayBack(new Array(5))
Lodash is a comprehensive utility library that provides a wide range of functions for working with arrays, objects, strings, etc. It includes methods like _.toArray which can convert values to arrays, similar to array-back, but it also offers a much larger set of utilities for different purposes.
Arrify is a minimalistic package that converts a non-array value into an array. It is similar to array-back in its basic functionality but does not offer additional features like flattening nested arrays or handling sparse arrays.
