+# place
+
+> Replace elements of an array with provided values according to a provided mask array.
+
+<section class="usage">
+
+## Usage
+
+```javascript
+var place = require( '@stdlib/array/place' );
+```
+
+#### place( x, mask, values\[, options] )
+
+Replaces elements of an array with provided values according to a provided mask array.
+
+```javascript
+var x = [ 1, 2, 3, 4 ];
+
+var out = place( x, [ 0, 1, 0, 1 ], [ 20, 40 ] );
+// returns [ 1, 20, 3, 40 ]
+
+var bool = ( out === x );
+// returns true
+```
+
+The function supports the following parameters:
+
+-   **x**: input array.
+-   **mask**: mask array.
+-   **values**: values to set.
+-   **options**: function options.
+
+The function supports the following options:
+
+-   **mode**: string specifying behavior when the number of `values` does not equal the number of truthy `mask` values. Default: `'repeat'`.
+
+The function supports the following modes:
+
+-   `'strict'`: specifies that the function must raise an exception when the number of `values` does not **exactly** equal the number of truthy `mask` values.
+-   `'non_strict'`: specifies that the function must raise an exception when the function is provided insufficient `values` to satisfy the `mask` array.
+-   `'strict_broadcast'`: specifies that the function must broadcast a single-element `values` array and otherwise raise an exception when the number of `values` does not **exactly** equal the number of truthy `mask` values.
+-   `'broadcast'`: specifies that the function must broadcast a single-element `values` array and otherwise raise an exception when the function is provided insufficient `values` to satisfy the `mask` array.
+-   `'repeat'`: specifies that the function must reuse provided `values` when replacing elements in `x` in order to satisfy the `mask` array.
+
+In broadcasting modes, the function supports broadcasting a `values` array containing a single element against the number of truthy values in the `mask` array.
+
+```javascript
+var x = [ 1, 2, 3, 4 ];
+
+var out = place( x, [ 0, 1, 0, 1 ], [ 20 ], {
+    'mode': 'strict_broadcast'
+});
+// returns [ 1, 20, 3, 20 ]
+
+var bool = ( out === x );
+// returns true
+```
+
+In repeat mode, the function supports recycling elements in a `values` array to satisfy the number of truthy values in the `mask` array.
+
+```javascript
+var x = [ 1, 2, 3, 4 ];
+
+var out = place( x, [ 1, 1, 0, 1 ], [ 20, 40 ], {
+    'mode': 'repeat'
+});
+// returns [ 20, 40, 3, 20 ]
+
+var bool = ( out === x );
+// returns true
+```
+

+
+<!-- /.usage -->
+
+<section class="notes">
+
+## Notes
+
+-   The function mutates the input array `x`.
+-   If a `mask` array element is truthy, the corresponding element in `x` is **replaced**; otherwise, the corresponding element in `x` is "masked" and thus left unchanged.
+-   The `values` array must have a [data type][@stdlib/array/dtypes] which can be [safely cast][@stdlib/array/safe-casts] to the input array data type. Floating-point data types (both real and complex) are allowed to downcast to a lower precision data type of the [same kind][@stdlib/array/same-kind-casts] (e.g., element values from a `'float64'` values array can be assigned to corresponding elements in a `'float32'` input array).

+{{alias}}( x, mask, values[, options] )
+    Replaces elements of an array with provided values according to a provided

+
+    In repeat mode, the function supports recycling elements in a values array
+    to satisfy the number of truthy values in the mask array.

+
+    Parameters
+    ----------
+    x: ArrayLikeObject
+        Input array.
+
+    mask: ArrayLikeObject
+        Mask array. If a mask array element is truthy, the corresponding element
+        in `x` is *replaced*; otherwise, the corresponding element in `x` is
+        "masked" and thus left unchanged.
+
+    values: ArrayLikeObject
+        Values to set.
+
+    options: Object (optional)
+        Function options.
+
+    options.mode: string (optional)
+        String specifying behavior when the number of values to set does not
+        equal the number of truthy mask values. The function supports the
+        following modes:
+
+        - 'strict': specifies that the function must raise an exception when the

+        values.
+        - 'non_strict': specifies that the function must raise an exception when
+        the function is provided insufficient values to satisfy the mask array.
+        - 'strict_broadcast': specifies that the function must broadcast a
+        single-element values array and otherwise raise an exception when the
+        number of values does not **exactly** equal the number of truthy mask
+        values.
+        - 'broadcast': specifies that the function must broadcast a single-
+        element values array and otherwise raise an exception when the function
+        is provided insufficient values to satisfy the mask array.
+        - 'repeat': specifies that the function must reuse provided values when

+
+        Default: 'repeat'.

+        Input array.
+
+    Examples
+    --------
