+# --description--
+
+In this lab, you will create a function that performs a search and replace on the sentence using the arguments provided and then returns the new sentence.
+
+**Note:** Preserve the case of the first character in the original word when you are replacing it. For example if you mean to replace the word `Book` with the word `dog`, it should be replaced as `Dog`
+
+**Objective**: Fulfill the user stories below and get all the tests to pass to complete the lab.
+
+**User Stories:**
+
+1. You should create a function named `myReplace`.
+1. The `myReplace` function should take three arguments: a string, a word to be replaced, and the word to replace it with.
+1. The `myReplace` function should return the new string with the replacement.
+1. You should preserve the case of the first character in the original word when you are replacing it.
+
+# --hints--
+
+You should create a function named `myReplace`.
+
+```js
+assert.isFunction(myReplace);
+```
+
+`myReplace` should take three arguments.
+
+```js
+assert.lengthOf(myReplace, 3);
+```
+
+`myReplace("Let us go to the store", "store", "mall")` should return the string `Let us go to the mall`.
+
+```js
+assert.deepEqual(
+  myReplace('Let us go to the store', 'store', 'mall'),
+  'Let us go to the mall'
+);
+```
+
+`myReplace("He is Sleeping on the couch", "Sleeping", "sitting")` should return the string `He is Sitting on the couch`.
+
+```js
+assert.deepEqual(
+  myReplace('He is Sleeping on the couch', 'Sleeping', 'sitting'),
+  'He is Sitting on the couch'
+);
+```
+
+`myReplace("I think we should look up there", "up", "Down")` should return the string `I think we should look down there`.
+
+```js
+assert.deepEqual(
+  myReplace('I think we should look up there', 'up', 'Down'),
+  'I think we should look down there'
+);
+```
+
+`myReplace("This has a spellngi error", "spellngi", "spelling")` should return the string `This has a spelling error`.
+
+```js
+assert.deepEqual(
+  myReplace('This has a spellngi error', 'spellngi', 'spelling'),
+  'This has a spelling error'
+);
+```
+
+`myReplace("His name is Tom", "Tom", "john")` should return the string `His name is John`.
+
+```js
+assert.deepEqual(
+  myReplace('His name is Tom', 'Tom', 'john'),
+  'His name is John'
+);
+```
+
+`myReplace("Let us get back to more Coding", "Coding", "algorithms")` should return the string `Let us get back to more Algorithms`.
+
+```js
+assert.deepEqual(
+  myReplace('Let us get back to more Coding', 'Coding', 'algorithms'),
+  'Let us get back to more Algorithms'
+);
+```
