• Fast
• Small
• Fully tested
• Documented
• Purely functional
• Modern codebase

• /object – for objects
• /string – for strings
• /promise – for promises
• /array – for arrays or array-like objects
• /function – for functions – composition, currying and so on, also a set of simple functions (noop, T, F)
• /is – set of type checking methods
• / – root contains utilities which don't satisfy any of the above categories or are universal

import pathOr from '@tinkoff/utils/object/pathOr';
import compose from '@tinkoff/utils/function/compose';
import toLower from '@tinkoff/utils/string/toLower';
import map from '@tinkoff/utils/array/map'
const toLowerName = compose(
 toLower,
 pathOr(['name'], '')
);
const result = map(toLowerName)([{name: 'testA'}, {name: 'testb'}])
