![]() ![]() It's probably best to speak of JSOL, JavaScript Object Literals, at this point. In UTF-8, the number of leading 1 bits in the first byte, which may be 0 (for 1-byte ASCII characters), 2, 3, or 4, indicates the number of bytes in the character. The decodeURI () function decodes the URI by treating each escape sequence in the form XX as one UTF-8 code unit (one byte). The escape () function encodes special characters, with the exception of: - +. decodeURI () is a function property of the global object. If you have JSON data as part of a string, the best way to parse it is by using the JSON.parse method that’s part of the JavaScript standard since ECMAScript 5, and it’s provided by V8, the JavaScript engine that powers Node.js. Because JSON has no syntax space for annotating type metadata, in order to revive values that are not plain objects, you have to consider one of the following: Serialize the entire object to a string and prefix it with a type tag. But there are also a few userland JSON parsers which support a bit more Javascript expression syntax. it makes a string portable, so it can be transmitted across any network to any computer that supports ASCII characters. The first parameter is the JSON string to parse, and the optional second parameter is the function used to. The JSON.parse () method takes two parameters. The JSON.parse () method converts (or decodes) a string containing JSON data into a JavaScript object. How to parse JSON from a string, and how to read a JSON file in Node.js To parse JSON string in JavaScript, you can use the JSON.parse (string, function) method. ![]()
