+## Usage
+
+```javascript
+var everyOwnBy = require( '@stdlib/utils/every-own-by' );
+```
+
+#### everyOwnBy( collection, predicate\[, thisArg ] )
+
+Tests whether all `own` properties of an object pass a test implemented by a `predicate` function.
+
+```javascript
+function isPositive( value ) {
+    return ( value > 0 );
+}
+
+var obj = {
+    'a': 1,
+    'b': 2,
+    'c': 3,
+    'd': 4
+};
+
+var bool = everyOwnBy( obj, isPositive );
+// returns true
+```
+
+If a `predicate` function returns a non-truthy value, the function **immediately** returns `false`.
+
+```javascript
+function isPositive( value ) {
+    return ( value > 0 );
+}
+
+var obj = {
+    'a': 1,
+    'b': -2,
+    'c': 3,
+    'd': 4
+};
+
+var bool = everyOwnBy( obj, isPositive );
+// returns false
+```
+
+The invoked `function` is provided three arguments:
+
+-   `value`: property value
+-   `key`: property key
+-   `obj`: input object
+
+To set the function execution context, provide a `thisArg`.
+
+```javascript
+function sum( value ) {
+    if ( value < 0 ) {
+        return false;
+    }
+    this.sum += value;
+    this.count += 1;
+    return true;
+}
+
+var obj = {
+    'a': 1,
+    'b': 2,
+    'c': 3
+};
+
+var context = {
+    'sum': 0,
+    'count': 0
+};
+
+var bool = everyOwnBy( obj, sum, context );
+// returns true
+
+var mean = context.sum / context.count;
+// returns 2
+```

+
+## Notes
+
+-   If the 1st argument is not an [`object`][mdn-object] or the second argument is not a fuction , the
+    function throws a Type Error.
+
+-   If provided an empty object, the function returns `true`.
+
+    ```javascript
+    function untrue() {
+        return false;
+    }
+    var bool = everyOwnBy( {}, untrue );
+    // returns true
+    ```
+
+-   The function differs from [`Array.prototype.every`][mdn-array-every] in the following ways:
+
+    -   The function does **not** skip `undefined` elements.
+
+        <!-- eslint-disable no-sparse-arrays, stdlib/doctest-marker -->
+
+        ```javascript
+        function log( value, index ) {
+            console.log( '%s: %s', index, value );
+            return true;
+        }
+
+        var obj = {
+            'a': 1,
+            'b': NaN,
+            'c': 3
+        };
+
+        var bool = everyOwnBy( obj, log );
+        /* =>
+            a: 1
+            b: undefined
+            c: 3
+        */
