Whether the data type is an underlying type

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.isPrimitive(v)

whether it is a reference type or via a type constructed by new

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.isObject(obj)

Is it a Promise function

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.isPromise(val)

convert to number

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.toNumber(val)

The object to inspect

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.isPlainObject(obj)

convert to string

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.toString(val)

Convert an array-like object to an array

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.toArray(list, start)

assign attributes to the target object

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.extend(to, _from)

Merge an array of objects into an object

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.toObject(arr)

camel case shortened dash separator

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.capitalize(str)

camel case shortened dash separator

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.hyphenate(str)

Change dash to camel case

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.camelize(str)

import {
    
     ToolkitUseShared } from 'toolkit-use/dist/shared/index.esm'
ToolkitUseShared.remove(arr, item)

function is executed only once
