Simple JSON pointer walking on javascript objects with no error handling. A super simplified version of https://github.com/json-schema-spec/json-pointer-typescript

walkPointer.ts

export const walkPointer = (object: { [key: string] }, pointer: string) => {
    let [, ...tokens] = pointer.split("/")
    tokens = tokens.map((token) => {
        return token.replace(/~1/g, "/").replace(/~0/g, "~");
    })
    let instance = object
    for (const token of tokens) {
        instance = instance[token]
    }
    return instance
}
