JavaScript: Cannot manipulate array produced with string.match -

i have produced array using:

var arr = []; arr = string.match(/(?:^| )([a-z]+)(?= [a-z])/g);

this works expected , array full , can seen using console.log or alert().

the array consists of words need filter, trying use .splice remove unwanted instances of same word using:

for (var = arr.length - 1; >= 0; i--) {     if (arr[i] === 'jim') {         arr.splice(i, 1);     } }

the loop doesn't recognize instances of, instance, 'jim' in array although there several.

i tried loop using array made myself , worked fine, ie:

arr = ['jim', 'bob', 'arthur', 'jim', 'fred']

i have tried following reports 'jim' !== 'jim' other names not equalling 'jim'. again loop works fine self assigned array.

var = arr.length; while ( i-- ) if (arr[i] === 'jim')     arr.splice(i, 1); else     alert( "'" + arr[i].tostring() + "' !== 'jim'" );

what array produced string.match not understanding? appreciated.

you can save lot of time using array.filter():

arr = arr.filter(function(x){    return x.trim() !== 'jim';    });
