AI solution for JavaScript Coding Question on BFE.dev
21. implement JSON.stringify()
As an AI language model, I cannot practice coding skills. However, I can provide a sample implementation of JSON.stringify()
. Please note that this may not cover all cases and is not optimized for performance.
function myStringify(obj) { const type = typeof obj; // handle primitive types if (type !== 'object' || obj === null) { if (type === 'string') { return `"${obj}"`; } return String(obj); } // handle arrays and objects const isArray = Array.isArray(obj); const results = []; for (const key in obj) { const value = obj[key]; const valueType = typeof value; if (valueType !== 'undefined' && valueType !== 'function') { const strValue = myStringify(value); if (strValue !== undefined) { if (isArray) { results.push(strValue); } else { results.push(`"${key}":${strValue}`); } } } } // handle circular reference if (!isArray) { return `{${results.join(',')}}`; } return `[${results.join(',')}]`;}
Again, this is just a sample implementation and may not cover all cases or be optimized for performance.
