Babel Configuration Manager

Build a utility that manages Babel plugin configurations with support for different transformation assumptions.

Problem

Create a configuration manager that constructs valid Babel configurations and determines transformation modes based on assumption settings. The focus is on managing the setComputedProperties assumption which controls how computed object properties are transformed.

Requirements

Your implementation should:

1. Create a function buildBabelConfig(options) that accepts an options object and returns a Babel configuration
2. The options object should support an assumptions property with a setComputedProperties field
3. Include the computed properties plugin in the returned configuration
4. Create a function isRelaxedMode(config) that checks if the setComputedProperties assumption is enabled in a given config
5. Handle cases where assumptions are not provided (default to strict mode)

Test Cases

• When assumptions.setComputedProperties is true, isRelaxedMode returns true @test
• When assumptions.setComputedProperties is false, isRelaxedMode returns false @test
• When no assumptions are provided, isRelaxedMode returns false (strict mode default) @test
• The config returned by buildBabelConfig includes the computed properties plugin @test
