    just-safe-get

    Part of a library of zero-dependency npm modules that do just do one thing. Guilt-free utilities for every occasion.

    🍦 Try it

    npm install just-safe-get
    yarn add just-safe-get

    Get value at property, don't throw if parent is undefined

    import get from 'just-safe-get';
    
    const obj = {a: {aa: {aaa: 2}}, b: 4};
    
    get(obj, 'a.aa.aaa'); // 2
    get(obj, ['a', 'aa', 'aaa']); // 2
    
    get(obj, 'b.bb.bbb'); // undefined
    get(obj, ['b', 'bb', 'bbb']); // undefined
    
    get(obj.a, 'aa.aaa'); // 2
    get(obj.a, ['aa', 'aaa']); // 2
    
    get(obj.b, 'bb.bbb'); // undefined
    get(obj.b, ['bb', 'bbb']); // undefined
    
    get(obj.b, 'bb.bbb', 5); // 5
    get(obj.b, ['bb', 'bbb'], true); // true
    
    get(null, 'a'); // undefined
    get(undefined, ['a']); // undefined
    
    get(null, 'a', 42); // 42
    get(undefined, ['a'], 42); // 42
    
    const obj = {a: {}};
    const sym = Symbol();
    obj.a[sym] = 4;
    get(obj.a, sym); // 4
