substantive

Determine whether a given argument is both truthy and iterable.

[] and {} are truthy in JavaScript. By the same token, '0' is falsy. Etc...

Accounting for these idiosyncracies can be inconvenient, so this library provides a few simple helpers. E. g.

if (this.props.list && this.props.list.length) {
    // do something w/ list
}

becomes

if (substArr(this.props.list)) {
    // do something w/ list
}
