The walkTree function recursively traverses an object or array, executing functions or evaluating expressions at each level, and returns the resulting value. It is exported as a module for use in other parts of the application.
This code appears to be a function that evaluates templates or expressions and returns an array of results, which can be either plain results or objects with an evaluate method, depending on the input settings. The function takes an array of strings or an object with settings as input and returns an array of results based on the provided settings.
The evaluateDom function evaluates a given XPath query or CSS selector on a DOM document, catching errors and handling various query formats and types, including those with wildcards. It returns an array of node values or a single value (number, string, or boolean) depending on the query type.
This code is a JavaScript testing module that uses the esprima and escodegen libraries to parse and generate code, and the assert library to make assertions on the code's syntax. The module exports two test functions, testProgram and testSelect, which can be used to test the code's structure and behavior.
The code imports a function from a Core module and assigns it to the getBookmarksFromTakeout variable. It then conditionally executes a block of code that accesses and prints the links property of a nested object if the $ symbol is defined in the current scope.
The promiseOrResolve function returns a promise that resolves to the value of a specified property on an object, using an optional callback function if the property is undefined, or resolves to undefined if the property does not exist.
Here is a brief explanation of the function's behavior in two sentences:
The function checks if the object has the specified property, and if so, returns a resolved promise with the property value if it's not undefined. If the property is undefined, the function returns a promise that resolves the property value using the callback function.
The code defines a class hierarchy in JavaScript using ES6 class syntax, with a parentClass and childClass that extend each other, but is wrapped in an if statement that checks if a variable $ is defined, which may cause issues.
This module exports two functions, extend and override, which create a new class by inheriting properties from a parent class, allowing for property overriding and extension. The functions are demonstrated through example usage and unit tests, showcasing their functionality and flexibility.
This code provides a collection of functions (typeErrorTemplate, standardCompare, arrayCompare, objectCompare, and interface) for comparing and validating values against expected structures, with the ability to handle type mismatches and loose comparisons.
The code includes several functions for comparing and validating values, including standardCompare, arrayCompare, and objectCompare, which compare arrays and objects against expected structures. The typeErrorTemplate function is used to create custom error messages for type mismatches, and the interface function provides a general-purpose comparison function.
The code demonstrates the behavior of the myInterface and overrideClass functions, showing how they merge and override properties of an object. It tests how these functions handle property overrides, logging different values to the console depending on the object properties and their order of creation.
