Motivation:
Track object mutations during runtime and/or while debugging with intention to find expected or unexpected changes.
Note: this extension utilises content scripts, so after immediate installation or an update, make sure to refresh the inspected tab before using its functionality.
API:
// compare left and right arguments
jsdiff.diff(
{ a: 1, b: 1, c: 3 },
{ a: 1, b: 2, d: 3 }
);
// with a single argument behaves the same as `jsdiff.diffPush`
jsdiff.diff(Date.now());
// shifts sides - previous right side becomes left, new value becomes right
jsdiff.diffPush(Date.now());
// update left side only
jsdiff.diffLeft(Date.now());
// update right side only
jsdiff.diffRight(Date.now());
