Finding elements in an array based on a specific string contained within a property

Question

Finding elements in an array based on a specific string contained within a property

I am currently working on filtering JSON data to specifically search for job roles that begin with a particular string.

The structure of the JSON is as follows :

"periods": [
        {
            "periodName": "Week1",
            "teamName": "Tango",
            "roleName": "SoftwareEngineerII",
            "roleExperience": "2",
            "id": "cc1f6e14-40f6-4a79-8c66-5f3e773e0929"
        },
        ...
    ]

My goal is to extract roleNames starting with "Software" in order to list all Software Engineers and filter out other roles.

I am uncertain about how to implement a "starts with" or "contains" function in this scenario.

Answer №1

Have you ever wondered how to efficiently filter an array based on a string property value? One method is using regular expressions to check if a string contains another string:

var str = 'SoftwareEngineerII';
if (str.match(/^software/i)) {
    // it starts with 'software'
}

To apply this concept as a filter predicate, you can use the following code snippet:

var query = Enumerable.From(data.periods)
    .Where("!!$.roleName.match(/^software/i)")
    .ToArray();
