+# countIfs
+
+> Count the number of elements in the input arrays which pass the tests implemented by the predicate functions.
+
+
+
+
+
+
+
+
+
+
+
+## Usage
+
+```javascript
+var countIfs = require( '@stdlib/array/base/count-ifs' );
+```
+
+#### countIfs( x0, predicate0\[, x1, predicate1\[, x2, predicate2, ...]] )
+
+Counts the number of elements in the input arrays which pass the tests implemented by the predicate functions.
+
+```javascript
+function predicate0( value ) {
+ return ( value > 0 );
+}
+
+function predicate1( value ) {
+ return ( value < 3 );
+}
+
+var x0 = [ 0, 1, 0, 1, 2 ];
+var x1 = [ 2, 3, 1, 2, 5 ];
+
+var out = countIfs( x0, predicate0, x1, predicate1 );
+// returns 1
+```
+
+The `predicate` function is provided three arguments:
+
+- **value**: current array element.
+- **index**: current array element index.
+- **arr**: input array.
+
+
+
+
+
+
+
+
+
+## Notes
+
+- The function assumes that all input arrays have the same length.
+- The function supports array-like objects supporting the accessor protocol (e.g., [`Complex128Array`][@stdlib/array/complex128], [`Complex64Array`][@stdlib/array/complex64], etc).
+
+
+
+
+
+
+
+
+
+## Examples
+
+
+
+```javascript
+var discreteUniform = require( '@stdlib/random/array/discrete-uniform' );
+var isPositiveInteger = require( '@stdlib/assert/is-positive-integer' ).isPrimitive;
+var isNegativeInteger = require( '@stdlib/assert/is-negative-integer' ).isPrimitive;
+var naryFunction = require( '@stdlib/utils/nary-function' );
+var countIfs = require( '@stdlib/array/base/count-ifs' );
+
+var x = discreteUniform( 10, -5, 5, {
+ 'dtype': 'int32'
+});
+// returns
+
+var y = discreteUniform( 10, -5, 5, {
+ 'dtype': 'int32'
+});
+// returns
+
+var out = countIfs( x, naryFunction( isPositiveInteger, 1 ), y, naryFunction( isNegativeInteger, 1 ) ); // eslint-disable-line max-len
+// returns
+
+console.log( x );
+console.log( y );
+console.log( out );
+```
