Lars Bak is a Danish computer programmer. He is known as a JavaScript expert and for his work on virtual machines. He is currently employed by Google, having contributed to the Chrome browser by developing the V8 JavaScript engine. After years abroad, Lars Bak now lives near Aarhus in Denmark.

Bak studied at Aarhus University in Denmark, receiving an MS degree in computer science in 1988 after which he became active in designing and implementing object-oriented virtual machines.

Virtual machines

After participating in the design and implementation of the BETA Mjølner System, in 1991 he joined the Self group at Sun Microsystems Laboratories in Cupertino, California. During his time there, he developed a programming environment for Self and added several enhancements to the virtual machine.

In 1994, he joined LongView Technologies LLC, where he designed and implemented high performance virtual machines for both Smalltalk and Java. After Sun Microsystems acquired LongView in 1997, Bak became engineering manager and technical lead in the HotSpot team at Sun's Java Software Division where he developed a high-performance Java virtual machine.

In 2002, after returning to Aarhus, Denmark, Bak founded OOVM, a company which developed software for mobile phones. In 2004, he sold it to a Swiss company, Esmertec.

In 2004, Bak joined Google to work on the Chrome browser. He did not return to the United States, preferring to work in Denmark where his daughters were also receiving their education. With a team of 12 engineers, Bak has been coordinating the development of the V8 JavaScript interpreter for Chrome, named after the powerful automobile engine.

Bak has also co-developed the Dart programming language presented at the 2011 Goto conference in Aarhus, Denmark.

Bak holds 18 U.S. software patents in the field of virtual machines programming. In 2010, after Oracle bought Sun and with Lars Bak now working for Google, Oracle sued Google for infringing on several software patents and amongst them was the "Interpreting Functions Utilizing a Hybrid of Virtual and Native Machine Instructions" patent filed by Lars Bak et al.
