Script Preparation code:

var acts = "BRA|BRA|FLR|VSL|BRA".split("|");

Tests:

For loop
for (var i = 0; i < acts.length -1; i++) { if (acts[i] == "BRA") acts.splice(i, 1); }
While loop
var i = acts.length; while (i--) { if (acts[i] == "BRA") acts.splice(i, 1); }
Map loop
acts.map((act,i)=>{ if (act == "BRA") acts.splice(i, 1); })
