From 04d8d249600bf7b350454175c521e0c251785956 Mon Sep 17 00:00:00 2001 From: rhysd Date: Tue, 13 Jul 2021 23:05:17 +0900 Subject: [PATCH] misc/wasm: enable ECMAScript strict mode Current wasm_exec.js does not enable ECMAScript strict mode. But it is recommended to be enabled because it 1. eliminates some ECMAScript silent errors by changing them to throw errors 2. fixes mistakes that make it difficult for JavaScript engines to perform optimizations 3. prohibits some syntax likely to be defined in future versions of ECMAScript This commit enables ECMAScript strict mode in wasm_exec.js following the transition guide: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Strict_mode/Transitioning_to_strict_mode Fixes #47116 Change-Id: Ib8ffceee37e9127698fb51304241f1e429efe83e Reviewed-on: https://go-review.googlesource.com/c/go/+/334269 Reviewed-by: Richard Musiol Reviewed-by: Cherry Mui Trust: Richard Musiol Run-TryBot: Cherry Mui TryBot-Result: Go Bot --- misc/wasm/wasm_exec.js | 1 + 1 file changed, 1 insertion(+) diff --git a/misc/wasm/wasm_exec.js b/misc/wasm/wasm_exec.js index 231185a123..22b19fbe80 100644 --- a/misc/wasm/wasm_exec.js +++ b/misc/wasm/wasm_exec.js @@ -1,6 +1,7 @@ // Copyright 2018 The Go Authors.
