I have a situation where I have to split a string by checking a condition whether a string begins with any of this character "<= | >= | = | !=" 

* `=>value` desired result `[=>,value]`
* `>=value` desired result `[>=,value]`
* `somevalue` desired result `[somevalue]`

My attempt

```
var string1 = '<=value';
var splitString = string1.split(/\s+(?:<=|>=|=|!=)\s+/);
console.log(splitString);

```
