one with not limited support.

var key = 'key1';
var value = 'value1';

//How to dynamically add key and value to a Object
var obj = {}
obj[key] = value

where i1 ,i2 ,i3,s1,s2 and s3 also dynamic values not like"i3"=xyz format.

var sampleInput = ['i1', 'i2', 'i3', 's1', 's2', 's3']

var _output = {}
for(var i=0;i<sampleInput.length;i++) {
    _output[sampleInput[i]] = sampleInput[i] + "value"
}

Sample output

Object {i1: "i1value", i2: "i2value", i3: "i3value", s1: "s1value", s2: "s2value"…}

JavaScript objects certainly do support that, both the key and value of the object can be variables. Using the syntax {[key]: value} For example:

var key = 'key1';
var value = 'value1';
var obj = { [key]: value }; // {key1: "value1"}

Specifically using [key] allows you to use the value of the variable key, rather than in the case of key: value, where it uses the actual name key.
