Sounds like this should work for you:
function kFormatter(num) {
return num > 999 ? (num/1000).toFixed(1) + 'k' : num
}
console.log(kFormatter(1200));
console.log(kFormatter(900));

Further improving Salman's Answer because it returns nFormatter(33000) as 33.0K
function nFormatter(num) {
if (num >= 1000000000) {
return (num / 1000000000).toFixed(1).replace(/\.0$/, '') + 'G';
}
if (num >= 1000000) {
return (num / 1000000).toFixed(1).replace(/\.0$/, '') + 'M';
}
if (num >= 1000) {
return (num / 1000).toFixed(1).replace(/\.0$/, '') + 'K';
}
return num;
}
now nFormatter(33000) = 33K

A more general version:
function nFormatter(num, digits) {
var si = [
{ value: 1E18, symbol: "E" },
{ value: 1E15, symbol: "P" },
{ value: 1E12, symbol: "T" },
{ value: 1E9, symbol: "G" },
{ value: 1E6, symbol: "M" },
{ value: 1E3, symbol: "k" }
], i;
for (i = 0; i < si.length; i++) {
if (num >= si[i].value) {
return (num / si[i].value).toFixed(digits).replace(/\.?0+$/, "") + si[i].symbol;
}
}
return num;
}
console.log(nFormatter(123, 1)); // 123
console.log(nFormatter(1234, 1)); // 1.2k
console.log(nFormatter(100000000, 1)); // 100M
console.log(nFormatter(299792458, 1)); // 299.8M
