设置多个 object 键的最简洁方法

Question

Hi I was working on a text parser and I was wondering if there was a clean to rewrite the following code. Concerning the way that an object's properties are set.

 //In the real case the parser returns varying result based on the param const parserResult = {'value':2,'syntaxError':false,'NaNError':false} const {value,syntaxError,NaNError} = parserResult const param = {someProperty:'any value'} //can have any properties //the problem under here param['value'] = value param['syntaxError'] = syntaxError param['NaNError'] = NaNError console.log(param)

Setting three properties like that one after an other is not all that eloquent does anyone now a cleaner solution? Thanks in advance. (complete code to test under here)

 const parseParam = param => { //In the real case the parser returns varying result based on the param const parserResult = {'value':2,'syntaxError':false,'NaNError':false} const {value,syntaxError,NaNError} = parserResult param['value'] = value param['syntaxError'] = syntaxError param['NaNError'] = NaNError return param } const parameters = [{someProperty:'test'},{someProperty:'someValue'}] const parsedParameters = parameters.map(parseParam) console.log(parsedParameters)

You should use spread operator for this kind of stuff.

It will look like this:

const param = {...parserResult, someProperty:'any value'}
