Thanks PMario,
The conditional testing indeed speeds things up.
I tried to remove about 20 fields that come from everywhere mainly
tsnip related.
Code ====
<script>
var field_name = 'tatata';
var tids =store.getTiddlers('title')
for ( i=1 ; i < tids.length ; i++ ) {
if ( tids[i].fields[field_name]) {
delete tids[i].fields[field_name];
store.saveTiddler(tids[i].title ........ tids[i].fields );
}
}
</script>
