runInThisContext
Runs the compiled code contained by the vm.Script
within the context of the current global
object. Running code does not have access to local scope, but does have access to the current global
object.
The following example compiles code that increments a global
variable then executes that code multiple times:
const vm = require('node:vm');
global.globalVar = 0;
const script = new vm.Script('globalVar += 1', { filename: 'myfile.vm' });
for (let i = 0; i < 1000; ++i) {
script.runInThisContext();
}
console.log(globalVar);
// 1000
