function-name-support

Feature detection for function names. See The names of functions in ES6 for background. Provides the same results as node-compat-table.

Installation

$ npm install --save function-name-support

Usage

const functionNameSupport = require('function-name-support')

support

A frozen object with boolean values. Compare with node-compat-table:

• function statements: functionStatements
• function expressions: functionExpressions
• new Function: newFunction
• bound functions: boundFunctions
• variables (function): functionVariables
• object methods (function): functionObjectMethods
• accessor properties: accessorProperties
• shorthand methods: shorthandMethods
• symbol-keyed methods: symbolKeyedMethods
• class statements: classStatements
• class expressions: classExpressions
• variables (class): classVariables
• object methods (class): classObjectMethods
• class prototype methods: classPrototypeMethods
• class static methods: classStaticMethods

hasFullSupport

A boolean indicating whether all known function name inferences are supported.

bitFlags

An integer that stores a serialization of the support object. Useful when storing a function name (or lack thereof) for later comparisons along with details on whether the function name was inferable at all.

isSubsetOf(otherFlags): boolean

Helper method for comparing bitFlags. Returns true if it is a subset of otherFlags.

isSupersetOf(otherFlags: number): boolean

Helper method for comparing bitFlags. Returns true if it is a superset of otherFlags.
