How to use toLowerCase() and Object.hasOwnProperty() Methods In Javascript
In this approach, the key is passed to the function and while comparing, use the toLowerCase() method to transform the passed key as well as the object’s key to lowercase. Then compare the keys and if they are the same then return their value.
Example: This example shows the use of the above-explained approach.
Javascript
let GFG_Object = { a: "Val_1", n: "Val_2", c: "Val_3", b: "Val_4",};function findVal(obj, prop) { prop = (prop + "").toLowerCase(); for (let p in obj) { if (obj.hasOwnProperty(p) && prop == (p + "").toLowerCase()) { return obj[p]; } }}function GFG_Fun() { let key = "A"; console.log("Key: '" + key + "'\nValue: '" + findVal(GFG_Object, key) + "'");}GFG_Fun(); |
Output
Key: 'A' Value: 'Val_1'
