Count the number of elements in an array that are equal to a specified value.
var countSameValue = require( '@stdlib/array/base/count-same-value' );Counts the number of elements in an array that are equal to a specified value.
var x = [ 0, 1, 0, 1, 2 ];
var out = countSameValue( x, 1 );
// returns 2In contrast to an implementation using the strict equality operator ===, the function distinguishes between +0 and -0 and treats NaNs as the same value.
var x = [ NaN, NaN, NaN ];
var out = countSameValue( x, NaN );
// returns 3- The function uses the SameValue Algorithm as specified in ECMAScript 5.
