Use of numeric constants in interface definitions is not good practice for new specs. The WebRTC WG has resolved to move away from this:

In HTML, TextTrack.mode was recently changed to enumerations after similar feedback:

These are the members with numeric constants in the Web Audio API spec:

AudioBufferSourceNode.playbackState
AudioPannerNode.panningModel
AudioPannerNode.distanceModel
BiquadFilterNode.type
Oscillator.type
Oscillator.playbackState
