  • Most of the browsers don't have setImmediate. setImmediate || setTimeout doesn't work and it throws setImmediate is not defined in this case, so we should check setImmediate with typeof. And some environments like Cloudflare Workers don't allow you to set setTimeout directly to another variable. https://github.com/graphql/dataloader/commit/3e62fbe7d42b7ab1ec54818a1491cb0107dd828a
