One of the functions I currently have incorporates lodash to compare two objects and determine if they are identical.
private checkForChanges(): boolean {
if (_.isEqual(this.definitionDetails, this.originalDetails) === true) {
return false;
} else {
return true;
}
}
I am curious if there is a method to display the properties that differ between the two objects (in case they are not equal).
I am utilizing both lodash and JQuery for this purpose.
Finding an easy way to compare objects can be tricky due to the various possibilities that exist. One helpful starting point is to examine the lodash source code for insights.
However, if you have a clear understanding of what exactly you are comparing, the task can become simpler. For instance, comparisons often involve plain, shallow objects. To delve deeper into this topic, you can explore resources such as How to determine equality for two JavaScript objects? and Object comparison in JavaScript.
Furthermore, remember that sometimes you may not need an if statement if all you require is to return the comparison result.
private checkForChanges(): boolean {
return !_.isEqual(this.definitionDetails, this.originalDetails);
}
Visit this link to learn more, there's no need to check for true in the if condition as Lodash will return either true or false.
function performChangeCheck(): boolean {
if (_.isEqual(this.newDefinition, this.oldDefinition)) {
return false;
} else {
return true;
}
}
