How to enable js features in substrate?

Question

I am trying to compile my substrate node but it is giving me the issue regarding js features:

error: the wasm*-unknown-unknown targets are not supported by default, you may need to enable the "js" feature. For more information see: https://docs.rs/getrandom/#webassembly-support
