Syntax

JSON.stringify

Converts JavaScript values to JSON strings; a method of the ECMAScript standard built-in object JSON. Available in JavaScript and Rust strategies; Python strategies use the standard json module.


    
    
    
JSON.stringify(obj)

Examples

Serialize an object to a JSON string and output it.

javascript
rust


    javascript
    
    
function main() {
    let s1 = {"num": "8754613216564987646512354656874651651358"}
    Log("JSON.stringify:", JSON.stringify(s1))
    // Output: JSON.stringify: {"num":"8754613216564987646512354656874651651358"}
    // JSON.stringify(s1) returns a string
}


    rust
    
    
fn main() {
    // Rust has no JSON.stringify; JsonValue's to_string() prints compact JSON (object keys sorted)
    let mut m = std::collections::BTreeMap::new();
    m.insert("num".to_string(),
        JsonValue::String("8754613216564987646512354656874651651358".to_string()));
    let s1 = JsonValue::Object(m);
    Log!("JSON.stringify:", s1.to_string());
    // Output: JSON.stringify: {"num":"8754613216564987646512354656874651651358"}
}
