Object To Process

💾 The object whose entries are to be retrieved. If the input is not an object, it will be coerced to an object.

Supported formats:
  ✓ Object
  ✓ Any (will be coerced)

Input Setup

Input Function (optional)

⚙️ Optional pre-processing function applied to the input before internal logic (e.g., convert object to string, normalize case). Internal transformations such as case handling will still apply afterward.

Result Handling

Output Function (optional)

⚙️ Optional function to apply to the result before returning it (e.g., str => str + ' €', val => val !== undefined for boolean conversion). Useful for chaining transformations on the output.

🎯 Using special value — click input to type instead

Test with:

Falsy undefined null "" empty 0 false NaN

Truthy true 42 "hello" {} empty [] empty {a:1} [1,2,3]

🔗 Result Handling — Chain Variables

Chain apply-mode variables to the output. Each variable receives the result of the previous one.

/**
 * Retrieves the entries of an object (key-value pairs).

 * @param {Object} data.src - The object whose entries are to be retrieved.
 * @param {Function|string} [data.out] - Optional output handler: function to transform result or string with format.
 *
 * Direct-mode specific parameters:
 * @param {Function} [data.pre] - Optional pre-processor function to transform src before getting entries.
 * 
 * @returns {Array} An array of key-value pairs of the provided object, where each entry is an array [key, value].
