Not able to change keys in JavaScipt dictionary-CodePudding

I am a beginner, i want to replace spaces with hyphen from keys of javascript dictionary and get the keys back in dictionary

eg. In nameVars = {"my name is":"aman", "age":22, "my ed":"btech"} I want resultant dictionary to be, nameVars = {"my-name-is":"aman", "age":22, "my-ed":"btech"} I am doing it using

for(const [key, value] of Object.entries(nameVars)){ key.replace(/\s /g,"-") }

but my output is still same keys are not changing, please help i dont know javascript.

CodePudding user response：

You modify the names of the keys but never add the modified keys back to to the object. You can approach your problem like this:

for(const [oldKey, value] of Object.entries(nameVars)){    
    const newKey = oldKey.replace(/\s /g,"-");
    // add the entry with the new key
    nameVars[newKey] = value;
    // delete the old entry
    delete nameVars[oldKey];
}

You should replace the content of the Object

var nameVars = {"my name is":"aman", "age":22, "my ed":"btech"}

for (const [key, value] of Object.entries(nameVars)) {
  if(key.includes(" ")){
    const newKey = key.replace(/\s /g,"-")
    nameVars[newKey] = value;
    delete nameVars[key]
  }
}
