Having just finished a small form, I realized that my current implementation of findIndex is not compatible with IE.
Let's take a look at an example of the problem:
var people = [
{name:"Mike", age:"25"},
{name:"Bill", age:"35"},
{name:"Terry", age:"44"}
];
console.log(people.findIndex(x => x.name=="Bill" ));
Is there a quick and efficient solution to address this compatibility issue in Internet Explorer?
discover browser compatibility for index support
Chrome 45.0 and higher: Supported
Firefox 25.0 and higher: Supported
Internet Explorer: Not supported
Microsoft Edge: Supported
Opera: Supported
Safari 7.1 and higher: Supported
To ensure compatibility across all browsers, consider modifying your code as shown below:
var index;
for(var i=0;i<people.length;i++){
if(people[i].name == 'billi'){
index = i
}
}
Additional information
this works great on Internet Explorer
people.findIndex(function(person){ person.name=="Bill" }));
