 # toolbox
 
-Toolbox is a golang base common library
+Toolbox is a golang base common library.
+
+util is short for "utility", typically referring to general-purpose tool functions and methods that are independent of specific business logic.
+
+The diference between utils and kits is that the utils is a collection of functions, without any dependencies.
+
+• Characteristics:
+    • Lightweight, focused on specific small functions or independent functional points
+    • No clear domain restrictions, usually consisting of scattered utility functions
+    • Commonly used to support higher-level business logic
+
+• Usage Scenarios:
+    • Handling common tasks such as string operations, date formatting, data conversion, etc.
+    • Independent of specific business logic or context
+
+• Examples:
+    • Node.js util module: provides general utility functions like util.promisify, util.format
+    • lodash utility library: includes many common utility functions like deep copy, array deduplication, etc.
