Ramda 0.29.1 assocPath pathOr behavior non-object intermediate path node

💡 Result:

In Ramda 0.29.1, the behaviors of assocPath and pathOr regarding non-object intermediate paths differ fundamentally based on their purposes: construction vs. retrieval [1][2]. assocPath Behavior When assocPath encounters a missing or non-object value at an intermediate path level, it creates a new structure to accommodate the specified path [3][2]. To determine what type of structure to create (an Array or an Object), assocPath inspects the next key in the path: If the next key is an integer (e.g., 0, 1, 4), Ramda creates an Array [4][3]. If the next key is not an integer (e.g., 'a', 'key'), Ramda creates an Object [3]. For example: R.assocPath(['a', 'b', 'c'], 42, {a: 5}); // => {a: {b: {c: 42}}} (replaces primitive 5 with an object) [1][2] R.assocPath(['a', 1, 'c'], 42, {a: []}); // => {a: [undefined, {c: 42}]} (creates index 1 as an object within an array) [2] pathOr Behavior pathOr is designed for safe data retrieval and does not create structures [5]. If any part of the path is missing or does not exist on the object, pathOr will immediately return the provided default value [5]. Important nuances for pathOr: It evaluates whether a path exists by checking if the object "has" the property, but its handling of null/undefined values has historically been a subject of internal debate [5][6]. It returns the default value if the path cannot be resolved (i.e., it is effectively "missing") [5]. It is generally inconsistent with propOr regarding how they treat keys that exist but are explicitly set to undefined, a known point of contention in the library [7][5]. Summary of Key Differences: - assocPath is constructive: It forces the object structure to match the provided path by overwriting primitives or missing nodes [1][2]. - pathOr is retrieval-only: It never modifies the source object and simply falls back to the default value if the path is not found [5].

Preserve non-object intermediate properties.

When property is a.b and properties.a is "keep", pathOr returns "0". assocPath then replaces a with an object, and upsertProfile persists the replacement through ProfileBuffer. Skip the update when an intermediate path value is not an object. Use 0 only when the target leaf is absent.

the property update logic around pathOr and assocPath to skip updates when any
intermediate path segment is a non-object value, preserving existing data such

absent, then continue persisting valid updates through upsertProfile and
ProfileBuffer.

Use strict numeric validation. adjustProfileProperty reads arbitrary profile-property values and passes the leaf value to Number.parseInt. Therefore, "12abc" becomes 12 and "1.5" becomes 1, then the handler persists the incorrect adjustment. Validate the value with Number(...), a non-empty check, and Number.isFinite(...) before updating.

Serialize concurrent adjustments for one profile.

Two requests can both read a missing profile, calculate from 0, and upsert the same resulting snapshot. Under the supplied latest-row-wins contract, one increment or decrement is lost. Use an atomic adjustment or serialize updates per profile before writing the snapshot.
