javascript remove where json contains string instead of equals

Question

This code currently searches the result array for where the name is "abc" and removes the entire index. How can I make it so it checks for name contains "abc". ie. name could be "abcd" and would still be removed.

var i;
for (i = result.length; i--;) {
  if (result[i].name === "abc") { 
    result.splice(i, 1);
  }
}

result is a JSON like
[{"name": "aaa", "number": "123"},{"name": "abc", "number": "456"},{"name": "abcd", "number": "789"},]

You can use filter and include to get the result you want

 var array = [{"name": "aaa", "number": "123"},{"name": "abc", "number": "456"},{"name": "abcd", "number": "789"}]
 
 var result = array.filter(item => !item.name.includes("abc"));
 console.log(result)

Note to OP ► .includes() does not work in Internet Explorer. Just in case you are using it.

To make it IE compatible you'd have to do something like array.filter(function(item){return item.name.indexOf("abc")});

@AndrewBone a small shim is also possible. jsfiddle.net/jhrrpcus

result[i].name.indexOf('abc') === 0

Essentially testing that the name starts with abc.

If you want it to just simply be in the name you can do just

result[i].name.indexOf('abc') > -1

"abc".startsWith("a") // true and "abc".includes("b") // true, more elegant than indexOf

Jeremy Thille Over a year ago

starts with is a subset of contains, but not the whole set of possibilities.

@JeremyThille as Nope mentioned in the other answer, includes is not supported in IE. caniuse.com/#search=include

This works for me. Can it also be done for where the name does not include "abc"?

Taplar Over a year ago

@albinosilver < 0 or === -1 would be the not includes conditional
