babel-preset-es2015-nostrict

A Babel preset that includes all ES2015 plugins but suppresses the automatic insertion of 'use strict' at the top of compiled modules. This is useful for projects that need to avoid strict mode globally (e.g., when concatenating scripts or using non-strict dependencies). The preset mirrors babel-preset-es2015 (v6.6.2) but without the strict-mode directive. It was released in 2015-2016 as part of the Babel 6 ecosystem. This package is now obsolete; Babel 7+ deprecates presets like this in favor of @babel/preset-env with the 'modules' and 'config' options. Key differentiator: removes strict-mode enforcement for legacy code compatibility.
