  constructor(private obj: ObjectUtils) { }
  
  myMethod(): void {
    this.obj.deepGet({a: {b: 42}}, 'a.b');       // 42
    this.obj.deepClone({a: 1});                  // {a: 1}
  }
}

Methods

| Method | Description | Example | |--------|-------------|---------| | deepGet | Get nested value by path | {a:{b:42}}, 'a.b' → 42 | | deepSet | Set nested value by path | obj, 'a.b', 42 → obj.a.b = 42 | | deepClone | Deep clone object/array | {a:1} → {a:1} | | clone | Alias for deepClone | {a:1} → {a:1} | | merge | Deeply merge multiple objects | {a:1}, {b:2} → {a:1,b:2} | | omit | Create object without keys | {a:1,b:2}, ['b'] → {a:1} | | pick | Create object with only keys | {a:1,b:2}, ['a'] → {a:1} | | isEmpty | Check if value/object is empty | {} → true | | isEqual | Deep equality comparison | obj1, obj2 → true/false | | keys | Get object keys | {a:1} → ['a'] | | values | Get object values | {a:1} → [1] | | entries | Get object [key, value] pairs | {a:1} → [['a', 1]] | | has | Check if path exists | obj, 'a.b' → true/false | | size | Get number of object properties | {a:1, b:2} → 2 | | mapValues | Map values using callback | {a:1}, v => v*2 → {a:2} | | invert | Swap keys and values | {a:'b'} → {b:'a'} |
