array functions tutorial part II
Third function is called searchCount, simply beacuse it counts number of wor in array. It goes something like this:
function searchCount(wor, arr){
var count = 0;
for(i=0; i< arr.length; i=i+1){
if(arr[i ]==wor){
count += 1;
}
}
return count;
}
Another function is union. If you have two arrays, union will return new array which consist of word that exists in both arrays.
function union(arr1, arr2){ var arr3 = new Array();
count = 0;
for(i=0; i< arr1.length; i=i+1){
for(j=0; j< arr2.length; j=j+1){
if(arr1[i ]== arr2[ j]){
arr3[count ] = arr1[ i];
count+=1;
}
}
}
return arr3;
}
One more important thing. Data type in these functions dont have to be String, it can be any type. For more strict evaluation, you can put === instead of ==.- end of part II -
