remove item from array javascript

Question

I was trying to remove some items from an array ,

Array.prototype.remove = function(from, to) { var rest = this.slice((to || from) + 1 || this.length); this.length = from < 0 ? this.length + from : from; return this.push.apply(this, rest); }; var BOM = [0,1,0,1,0,1,1]; var IDLEN = BOM.length; for(var i = 0; i < IDLEN ;++i) { if( BOM[i] == 1) { BOM.remove(i); //IDLEN--; } } 

RESULT IS

 BOM = [0,0,0,1]; 

expected result is

 BOM = [0,0,0]; 

its looks like i am doing something wrong , Please help me.

Thanks.

Answer 1

try this

var BOM = [0,1,0,1,0,1,1]; for(var i = 0; i < BOM.length;i++){ if( BOM[i] == 1) { BOM.splice(i,1); i--; } } console.log(BOM); 

Answer 2

Try using filter: var test1 = ['a','b','c','d']; var test2 = ['b','c']; test2.forEach(removeItem => { test1 = test1.filter(item => item != removeItem); }) console.log('Modified array',test1); 

Answer 3

Array.prototype.remove= function(){ var what, a= arguments, L= a.length, ax; while(L && this.length){ what= a[--L]; while((ax= this.indexOf(what))!= -1){ this.splice(ax, 1); } } return this; } 

Call this function

for(var i = 0; i < BOM.length; i++) { if(BOM[i] === 1) BOM.remove(BOM[i]); }
