array-back

What is array-back?

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.

What are array-back's main functionalities?

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))
