What was chrome programmed in

For example, V8 must JIT-compile differently for the different hardware it runs on; and the UI and feature-set is modified to suite the host as well. However, Chrome does not use V8 on iOS. Instead it uses JavaScriptCore.

The same holds true for Firefox and is a result of much stricter Apple rules on dynamic native code execution. Chrome on android and iOS both use a lightweight version chromium browser from the chromium project and yes it uses the v8 JavaScript interpreter. Though I don't think there is much difference in higher level implementation of V8 apart from the platform ones. Stack Overflow for Teams — Collaborate and share knowledge with a private group.

The shell provides powerful features, but the flip side is that security pitfalls are tricky to avoid. Think twice whether your shell statements can have unintended side effects, in particular if your script runs with full privileges as is the case with init scripts.

The Python interpreter is not included in production Chrome OS system images, but Python is used heavily for development and testing. We largely follow the Google Python style guide , but see the Chromium OS Python style guidelines for important differences, particularly around indenting and naming.

For tests, see the autotest coding style. The Chromium OS testing site is the main repository of information about testing. Unit tests should be added alongside new code. It's important to design your code with testability in mind, as adding tests after-the-fact often requires heavy refactoring.

Good unit tests are fast, lightweight, reliable, and easy to run within the chroot as part of your development workflow. See the Best practices for writing Chrome OS unit tests document for more guidance on writing good unit tests.

Autotest is used to run tests on live Chrome OS systems. Earn AdMob. Google Developer Groups. Google Developer Student Clubs. Product Index. All Products Develop Grow Earn. Google is committed to advancing racial equity for Black communities.
