Introduction to JSON
JSON (JavaScript Object notation) is a lightweight data interchange format. It is based on a subset of ECMAScript. JSON uses a completely language-independent text format, but it also uses a family of C-language (c, C + +, C #, Java, JavaScript, Perl, Python, and so on). These features make JSON a
client application.Fortunately, there is a better way.Using JSONJSON, also known as JavaScript Object notation, is a lightweight syntax for describing data. JSON is elegant because it is a subset of the JavaScript language. Next you'll see why it's so important. First, compare the JSON and XML syntax.Both JSON and XML use structured methods to describe the data.
JSON (JavaScript Object Notation)is a lightweight data interchange format. It is based on a subset of ECMAScript. JSON takes a completely language-independent text format, but also uses a similar idiom to the C language family (c, C + +, C #, Java, JavaScript, Perl, Python, and so on). These features make JSON an ideal data exchange language. Easy to read and wri
