Demo

Usage

You can execute any JavaScript code by first selecting it and then running Eval and Replace: JS from the command palette (or by selecting it and using the default keybinding, Ctrl + Shift + J)

Multiple selections & pre-initialized values

You can evaluate multiple expressions selected seperately, and each will be replaced seperately, however: the same context is used for all selections, so you can reuse variables.

Additionally you have access to these pre-initialized global functions and variables:

• i, j, n, x, y, z: initialized with 0
• a, s: initialized with ''
• PI: Alias for Math.PI (etc. for other Math properties & methods)
• randomInt(min: number, max: number): generates a random integer between min and max (inclusive of both)

Note that you can add your own custom pre-initialized data through the eval-and-replace.preinitializedScript setting.
